RECmaxCVM. Protect, reclose and measure. Avoid indirect costs to your installations by using reclosing systems

on .

Recent developments in electrical installations have given power supply continuity top priority among all users of the electrical network, especially in those industrial sectors where outages cause serious economic losses, either directly or indirectly. We are talking about plants whose industrial processes are vital, the telecommunications industry, the food and pharmaceutical industries, among others.

Power supply continuity is closely related to devices offering electric protection, another fundamental aspect of any electrical installation Protection devices are responsible for supply outages in our own installation, which may affect several lines depending on which protection device is involved.

Ideally, protection devices should trigger whenever there is a safety risk to those operating the installations or a risk of damaging machinery connected to the network. Having said this, protection devices not only trigger in the event of a real threat, but more often than not transient disturbances with no serious effect on the installation are responsible, and this type of scenario is precisely when protection and power supply continuity come into play.

As a result of the growing demand for solutions that aim to guarantee power supply continuity, devices have been developed to keep installations permanently working without risking personal safety or damage to machinery. Protection devices with self-reclosing systems are responsible for restoring power when there are no longer any risks of doing so. Thanks to such devices, the inconvenience, unnecessary costs and time wasted (in addition to the inherent output losses due to power supply shutdown) in manually switching circuit breakers back on are avoided, especially when they are sometimes located far away, are inaccessible or simply difficult to reach.

They have a wide range of applications since they are suitable for all isolated, mainly unsupervised installations, but where a good balance between safety and power supply continuity is of paramount importance.

What are the causes of untimely circuit breaker tripping?

Reasons for untimely tripping vary widely. From the presence of harmonic currents in the network to the variable behaviour of loads in the installation, including environmental factors such as lightning during a thunderstorm. As will be seen below, any tripping of protection devices in autonomous installations that are far away or difficult to reach leads to substantial losses for many industries.

Telecommunications industry

Telecommunications industry

Telecommunications centres for telephone, radio and television companies are often located on high ground like hills or mountainous areas to maximise the range they cover. When there are thunderstorms and lightning, any lightning that strikes areas adjacent to these centres could trip the earth leakage protection device. This event, though not causing any permanent system leakage, could render the telecommunications centre useless until a supervisor arrives to switch the circuit breaker back on. Bearing in mind the number of people affected by this type of situation, financial losses for telecommunications companies may reach tens of thousands of euros per minute.

The inconvenience and costs involved in bringing a technician to the area just to find out that the installation has not been seriously damaged must also be added to this cost.

Public lighting systems and traffic management
Public lighting systems and traffic management

In large cities, order largely depends on how traffic is managed. Correct synchronisation of traffic lights and signalling systems such as luminous panels are crucial for smooth traffic flow in large cities. Anything affecting elements that control traffic would lead to chaos, causing accidents or the busiest areas to come to a complete standstill.

Likewise, most public lighting systems operate independently and are difficult to monitor due to the presence of multiple lamp posts spread out everywhere. As in the case of traffic management, untimely tripping in this type of installation would affect a large number of people and constitute a serious road safety hazard.

Water and gas distribution systems

Water and gas distribution systems

Some water and gas supply phases take place in areas that are difficult to reach, thereby making it very complicated to restore supply. Furthermore, the typically slow response time of large companies to restore services could lead to outages lasting even longer.

Food sector companies
Food sector companies

Turning to other sectors such as food, we have an industry whose needs for continuous power supply are extremely demanding. Take the case of large supermarkets: this type of business cannot afford lengthy power cuts to lines where refrigerating chambers are connected, as this would adversely affect the state of the stored product and may even result in large quantities of goods being thrown away.

So what can we do to protect our installation without affecting power supply continuity?

Circutor's solution to the above-mentioned problems lies in the use of the RECmax CVM circuit breaker with self-reclosing earth leakage protection and inbuilt measurement.

Designed for power supply continuity

The RECmax CVM features an electric motor designed to operate the switch when reclosing. Reclosing options (sensitivity, delay, reclosure number, reclosure time intervals, reset times) are programmable and enable fully autonomous power recovery.

Protection continues to be a priority

The RECmax CVM includes an over-voltage and short-circuit protection device, and also offers earth leakage protection in the event of leakage in the installation. The device guarantees installation safety at all times.

What does CVM stand for?

The RECmax CVM features inbuilt measurement for over 250 electrical parameters, thereby enabling a much greater control over the installation's behaviour. The display shows the key variables in your installation, such as voltages, currents, powers, harmonic distortion, power factor... as well as important protection parameters: protection status, real-time leakage, total number of trips or number of trips per protection type. The device allows you to browse different menus using its keypad, which can also be used to configure various reclosing parameters: sensitivity, delay, reclosure number, reclosure time intervals, reset time.

RECmax CVM features inbuilt measurement for over 250 electrical parameters

Advantages of CIRCUTOR's RECmax CVM

Save time, space and money

The RECmax CVM's Plug&Play system minimises installation time to just a few minutes. Both the efficient MC measurement transformers and the WGC differential sensor are included in the kit, through which you simply need to feed the power cables, connect them to the device using the plug-in connection terminals, and the device is ready. The aforementioned wiring is all you need for the RECmax CVM to start operating, since it is self-powered through an internal connection to the circuit breaker.

Taking up just 7.5 modules of space for the 4-pole model and 5.5 modules for the 2-pole model, the RECmax CVM is a compact device suitable for installation in switchboards with limited available space.

The equivalent application with separate devices would require 3 more modules and cost 25% more.

Save time, space and money
Ultra-immunised

The ultra-immunised system, present in other products in Circutor's earth leakage protection range, offers the following advantages:

  • The earth leakage device triggers when reaching 85% of the threshold leakage value, which is when there is a serious risk to the installation and its users.
  • Immunity against high-frequency currents
  • Immunity against transient network variations
Installation control

Thanks to the RS-485 communications port, the RECmax CVM may be added to SCADA systems for remote device management, enabling in-depth analysis of device readings as well as remote configuration. The device features two configurable digital outputs, very useful for controlling alarms or other external systems.

By monitoring the unit, the status of the protection device may also be easily checked at all times, enabling remote intervention.

The backlight display, in keeping with other devices in our company range, allows protection device status to be instantly checked. In the event of tripping, the screen (normally green) changes to red in order to detect faults in the installation at a glance, displaying the value of the current that caused the system to trip.

Versatility

The RECmax CVM comes in 2-pole or 4-pole versions for all types of installations. Furthermore, the product range includes the possibility to choose from a 6A to 63A current range and a C or D trip curve.

RECmaxCVM

The above makes the RECmax CVM a very versatile product, an ideal device for:
  • SAVING: Maximises power supply continuity
  • SAFETY: Guarantees user safety and protects the installation's machinery.
  • MONITORING: Offers energy saving potential by monitoring, as well as detecting weak points in the installation that require preventive action.

Energy Management Systems and consumption analysis

on .

The growing importance of electricity costs in businesses or at home has sparked a keen interest in understanding this consumption.

If you want to save on energy costs, you have to discover the reality hidden behind every power socket. You can explore alternatives which will stop consumption figures from boosting the final amount to quantities beyond your budget.

Basics of electrical installations for energy optimisation

Before attempting to take any steps to reduce electricity costs, the internal electrical grid must be understood. There are three essential categories to be considered when analysing problems:

  1. The total power contracted. It is reflected in the electricity bill and follows a standard type of consumption that meets consumer needs.
  2. The pattern of consumption based on industrial or domestic usage. In practice, this means the installed devices and the energy each unit needs to consume to operate correctly.
  3. Energy consumption rate per device. This stems from the previous category. For example, it specifies the time used by each power consumption device. A fridge will usually consume a continuous amount, whereas a dishwasher will probably consume a different amount from month to month. If you are able to identify these variables, then it is easy to manage power consumption.

It is very useful and revealing to break down contracted power consumption per installed electrical appliance and usage times. If you are unable to find a decent alternative to your consumption, you can always compare rates and offers from electricity companies. All include a discount on electricity consumption subject to individual contract conditions that also need to be evaluated

Keys to understand and calculate electricity consumption

Your electricity consumption may be conveniently tracked by using measuring devices such as energy consumption analysers. Any deviation in the usual rate caused by a device's malfunction is immediately detected. It is as simple as comparing the amounts consumed by the same device for previous periods.

The analysis of over 250 electrical parameters with references to energy, cost and equivalence in emissions shows whether current regulations on Energy Efficiency are being complied with or not. The documentation provided allows you to quickly configure the system, enabling you to safely and reliably track the consumption of your private network. You no longer have to mentally calculate consumption since rates are conveniently updated and even different sources of power are recognised. This is the case, for example, with auxiliary power units or UPS (Uninterruptible Power Supply).

A definitive state-of-the art solution providing complete control over the operation of an electrical network. Corrective actions have been clearly indicated for any detected malfunctioning.

Spain, together with Germany, has the highest electricity rates in the European Union. The actions you take to save energy lower its effect on your budget by saving important costs in the medium and long term. The solutions to any doubts arising from this section may be found on commercial networks offering these products.

The Type 2 or Mennekes connector for electric vehicle charging

on .

There are several types of connectors for electric vehicle charging. In this article, we describe each of them, making special emphasis on Type 2 or Mennekes, which is the predominant in Europe.

Type 2 or Mennekes (IEC 62196-2)

Typo 2 or Mennekes (IEC 62196-2)

It is commonly known as Mennekes, which is the name of the first brand that commercialized it. It is approved as a European standard.

As the electric car becomes more widespread, many brands are adapting to use it in European territory. However, a valid solution is to use a cable with two connectors. Thus, at one end, the appropriate connector is placed on the car's recharging socket and at the other end, the European connector.

It is an AC charger used in a variety of EV models, such as BMW i3i8BYD E6Tesla Model SRenault Zoe, plug-in hybrid Volvo V60VW E-upAudi A3 E-tron, plug-in Mercedes S500, hybrid Plug-in VW Golf, Porsche Panamera and Renault Kangoo ZE.

Type 2 connectors allow single-phase charging up to 16 A and three-phase charging up to 63 A, which translates to a power output of 3.5 kW and 44kW, respectively.

Its pin distribution is similar to Type 1, but in this case, two more pins are included, which correspond to the two additional phases necessary for three-phase charging.

 


If you are thinking about purchasing an electric vehicle and you live in Europe, this is the connector that you will most likely be using.


 

Other types of connector to recharge the electric car

  • Schuko
    It is the usual plug you have at home or in the office. In addition to being in the vast majority of domestic applications, it is very common to find it on motorcycles and electric bicycles. It is also used in some electric cars, such as the Twizy.
  • Type 1 (SAE J1772)
    Type 1 (SAE J1772) This is the Japanese standard for electric vehicle charging in alternating current (also adopted by countries in North America and accepted by the EU). It is in models such as Opel AmperaNissan ENV200Nissan LeafMitsubishi iMievMitsubishi Outlander or Peugeot iON.
  • Type 3
    It was created in 2010, but it has lost the battle against the Type 2 model, and is currently in disuse.
  • CHʌdeMO
    CHʌdeMO It was developed by a Japanese association and is designed for rapid DC loads that can supply up to 50 kW of power with a current that can reach 125 A.
  • Combo 2 connector (IEC-62196-3)
    Combo 2 connector (IEC-62196-3) It offers the possibility of charging in modes 2, 3 and 4 through a single output. Vehicles from manufacturers like Audi, BMW, Porsche and Volkswagen incorporate it.

Spain ranks fifth for electric vehicle charging points

on .

Electric cars are an increasingly frequent sight in our cities. Spain is now the fifth most prolific country in Europe for zero-emission vehicles.

FD 5pais VE cargadorWhen sales of these vehicles began to take off, there were not so many charging points as there are now. Spain now has 3,856 public charging points for electric cars.

It is thanks to those charging points that Spain has the fifth largest infrastructure globally for these vehicles. The data were collected by Unieléctrica, based on figures from electromaps.com and the Spanish Institute of Statistics.

The United States occupies first place for infrastructure, followed by France in second, Germany in third and Holland in fourth.

New users of electric cars are recommended to find out all possible information from institutions and to ask in dealerships. Primary, they must be sure before buying whether they can charge their vehicle adequately in their location. The availability of charging points varies across the country. For example, in the region of Catalonia there are 939 charging points, and in Madrid there are 453.

Eco-friendly cars are becoming more popular across the globe. Numerous Governments across the world are supporting sustainable mobility. What once seemed impossible is now a reality; many companies are pursuing eco-friendly transport, and the number of private charging points is on the rise.

How do I charge my electric car?

All you need to do is connect your car to a charging point. You can usually find the cable in the boot of your electric vehicle. Once it is connected, the charging programme will begin automatically. The LED lights will indicate when charging begins and some cars have a charging current programme.

For the optimum charging of the battery of your electric car, you should be aware of the two different types of plugs. Around 30 models of zero-emission vehicles on the market have a type 2 “Mennekes” plug, which has been EU standard since 2013, designed by the alternative electrical charging company Mennekes.

For a quick charge, the Japanese electrical and automotive industry developed for 2019 the CHAdeMo connector. It is mostly used in Asia, but certain European electric car models are now using this kind of plug.

If you have an adaptor you can also charge your electric car battery at home, but only in an emergency, because domestic electricity infrastructure is not suitable for extended charging.

Recommendations for charging zero-emission vehicles

Tipo 2 ó Mennekes (IEC 62196-2)To fully charge your electric car battery, you need to ask two key questions: What kind of charging? What kind of plug?

Choose the charging mode (full or quick) according to your needs.
Get to know the models of electric cars and charging points in your city.

How to avoid penalties on electricity bills (industry and services)

on .

If you run a business, one of the things you will be concerned with is your electricity bill. You will no doubt have heard of reactive energy and how it can affect the cost of your final bill. But what exactly is this type of energy?

What is reactive energy?

So-called reactive energy is the electrical energy that certain electrical appliances and units take from and return to the grid without using it. This means it is not actual consumption, although there is a cost to utility companies as they have to generate and transport it, which is why this energy can be found on your bill, especially when it accounts for a high percentage of consumption.

This type of energy is mostly required by units that generate a magnetic field in order to work. While private properties may have practically no reactive energy consumption, for businesses it can be a significant expense and occasionally a source of problems.

There are steps you can take to lower the penalties imposed for the reactive energy required by the units you have installed, thus correcting the so-called power factor. This factor measures the ratio between active power (actual operating power) and the total power consumed or the apparent power. Its value will be 1 or less, representing the actual efficiency of the electricity consumption. The ideal power factor value is therefore 1, which would imply a better use of energy.

  


This type of energy is mostly required by units that
generate a magnetic field in order to work

 

How to cut your electricity bill by reducing reactive energy

There are different measures that can be implemented to bring the power factor value as close as possible to 1. One of the options you will have to consider, if you haven't already, is installing a capacitor bank, consisting mainly of a regulator, contactors and capacitors.

The presence of harmonics in the facility must also be assessed, installing a harmonic filter whenever necessary. These elements are generated as a result of a distortion of the electrical current caused by certain electronic units. The problem is that the resonance they can generate ends up causing damage, such as overheating or system degradation.

In any case, a thorough study of the electrical facility would have to be carried out and any possible damage, especially to the capacitors, repaired. You should therefore consult an expert who can advise you on the best options for your facility.

In short, reactive energy can be a major expense in a company's electricity bill, making it vital to reduce this type of consumption in order to save unnecessary costs. Please contact us if you would like an expert to review and study your facility with a view to cutting your electricity bills. Our experts will be happy to answer any questions you may have.

CVM-A1500A. Supply quality management in industry

on .

Continuity in supply of raw materials and the constant flow of resources to production processes have been crucial in preventing financial losses due to production stoppages. As is well known, in both industry and business, time is money.

Production stoppages bring with them financial losses and in most cases they are down to lack of planning, whether due to a logistics issue, lack of preventive maintenance or many other similar problems. There are numerous obvious and visible causes and also others which are harder to identify.

Poor power supply quality is one of them; you cannot see it and its impact may be as serious as any lack of raw material for your production processes. The technology of the machinery involved in these processes is increasingly sophisticated and delicate while the quality of the voltage waveform is taken for granted in most designs.

Many maintenance managers are called in when a machine stops working properly or just comes to a halt for no apparent reason. From then on the experience of the manager and their team comes into play to spot the fault or to restart the system. It is likely that the system will resume operating without any further incidents, meaning the real problem remains unknown and may crop up again at any time with no apparent cause.

There’s no doubt you are getting swells, dips or interruptions in the power supply, and it may be that the electronic systems’ circuit breakers bring the machinery to a halt to prevent damage which can turn out to be very expensive.

Protecting your system against these kinds of problems may also call for significant investment, yet everything depends on how often you have these problems and the impact they have on your operations.

An initial and much more affordable measure is installing a device which can detect and log those problems. With the information from this device you will be able to address the problem with greater chances of a successful outcome.

FD CVM-A1500 factory

Analysing the installation using network analysers

As we have seen, it is crucial to have real information about the status of the electricity network in order to be able to detect whether a production stoppage is due to the quality of the power supply. For this purpose, there are network analysers which can help maintenance managers to understand what is going on at any given time in order to make the best decision, either to avoid production stoppages or to mitigate their impact.

To try to make performing this task as easy as possible, Circutor has designed its CVM-A1500A power quality analyser. It will quickly report any network quality incidents which may occur in a facility so that action can be taken straightaway.

This model is certified under the IEC 61000-4-30 standard and detects faults in power supply quality in the waveform from the half cycle (from 10 ms in 50 Hz networks and 8.3 ms in 60 Hz networks), providing complete information to maintenance managers about the problem. By installing several units at key points in the installation you can get a clear idea of when, where and how a power supply quality problem has impacted it.

The CVM-A1500’s user interface and integrated Web server provide easy, convenient and intuitive access to information about any power quality problems identified.

You don’t have to be an expert to interpret its data

The downside when it comes to analysing network quality has always been the interpretation of data by a specialist engineer. Some installations have quality equipment installed but it is not used because users have difficulty in interpreting its data.

Quality analysers are normally “black boxes” which do not provide information if they are not connected via data interpretation software.

So in addition to needing computer skills to download their data you also have to know about their computer program for interpreting these data. If you additionally combine equipment from several manufacturers, then the task is even trickier.

That’s why Circutor has developed a model featuring browsing by colour screens to provide relevant information for decision making.

ITIC curve

The CVM-A1500A analyser shows the ITIC (also CBEMA and SEMIF 47) curve on the screen. With just three clicks on the equipment, any maintenance manager can display the ITIC curve.

This curve shows red triangles each time an event occurs, quickly displaying how many quality events there have been and how damaging they have been for the installation. This means you can swiftly see what kind of problem you are faced with.

If the triangles are in the green zone, this means that there have been events (power surges or voltage drops) which have not harmed the electronic equipment in your facility. However, if the triangles are in the red zone, this will mean a swell which has most likely damaged your electronic equipment. The closer the triangles are to the top left, the more damaging they will be due to their high value and duration. By contrast, if the triangles are in the yellow zone this means that there have been voltage drops. These voltage drops may impact electronic systems leading to rebooting or stoppage due to low voltage.

Just by glancing at this screen, any maintenance manager will know why there might have been a malfunction. Furthermore, if it is repeated regularly, they will have more information to install a system which mitigates the event’s impact thus avoiding production stoppages and hence financial losses.

ITIC Curve

Installation events

In addition to the curves we have discussed above, the equipment has an event counter which shows you how many there have been in each phase so you will know whether the problem always comes from the same phase or if it is repeated regularly. To get a closer look, you can use the analyser’s screen to review each event individually and view it in detail. With several clicks on its screen you enter the event and see in which phase it took place, what its voltage percentage is, what voltage there was before the event (this helps you see whether it was a fast event due to switching or a slow one due to overloading), how long it lasted (from the half cycle) and on what date and at what time it occurred. Plus you can always enter the event to see its associated waveform, showing the voltage sinusoid to see exactly when it happened.

Other parameters to be checked to ensure the proper operation of an installation

We have seen how voltage events may bring about production stoppage which leads to financial loss. Furthermore, power supply quality analysers can help us avoid future problems in the installation by checking other relevant parameters.

Harmonics

Harmonic decompositionThese devices show harmonic decomposition up to 63, and you can see what level of harmonic load you have in the installation. Harmonics can impact the installation’s performance and also trip a circuit breaker or lead to overheating or malfunction of electronic loads.

Unbalances

Quite often installations have uneven currents in the various phases due to poor load distribution or a subsequent line extension. This effect may lead to current flowing through the neutral wire. In these cases it is essential to measure the current flowing through the neutral conductor to avoid possible insulation failures which can cause breakage that leads to swells, thus damaging components of the installation. Furthermore, if the installation has its own distribution transformer, this may overheat resulting in premature ageing and changing its useful life. To avoid these hazards, the CVM-A1500 network analyser measures neutral current along with any unbalance in voltages and currents and reports any situation that may entail a risk for the installation both onscreen and by email.

Data display on a PC

The CVM-A1500A analyser has a web server with built-in memory. Any user can access the logged data on a web browser (Internet Explorer, Firefox, Google Chrome, etc.) to monitor all parameters in real time, produce graphs and tables, view quality events and waveforms and extract data easily in Excel without having to be an expert in power supply quality software. Plus the equipment can be integrated with our PowerStudio Energy Management Software (EMS) and can be integrated into a complete network with equipment for usage management to provide an overview of the installation’s entire status.

Access by web browser or PowerStudio software

Network quality at a glance

As we have seen, with the CVM-A1500A power supply quality analyser any user can have complete control of the parameters which may bring about a malfunction in any installation and also check where an electrical fault comes from, whether it be internal or external. By exporting data, maintenance managers can negotiate with the electric utility in case of a stoppage due to poor power supply quality or may even demand guarantees for all machines with anomalous operation as they can check whether the failure is the result of an external cause or due to malfunction of the machine itself.

REC4. Comfort at home, continuity in infrastructures

on .

Earth leakage protection is one of the most important systems in electrical installation safety.

Circuit breakers must always trip whenever a dangerous leakage level for humans is reached or they can cause economic losses to electrical installations. That said, these elements do not only trip on occasions caused by leakage in the installation, but due to external factors too, such as thunderstorms which frequently occur.

Self-reclosing RCCB devices are circuit-breakers with a built-in motor, whose function is to reclose if there is no permanent leakage in the installation.

This article presents a new design in Circutor's REC series, the REC4, as well as highlighting the benefits of installing such a device.

The device

FD REC4 3-en

The new REC4 is a development of its predecessor, REC3, in terms of size, while maintaining all its features. The device now takes up only a 3-module space, which means that it can be easily installed in new or existing electrical panels.

It is also the ideal solution for panels with limited space, replacing the standard earth leakage protection (2 modules) and the thermal magnetic circuit breaker (2 modules) with the REC4 (3 modules) and a unipolar thermal magnetic circuit breaker (1 module), also referred to as DPN. Automatic reclosing is therefore incorporated by taking up the same space, avoiding the need to enlarge the electrical panel.

REC4

The REC4 also includes the possibility to cancel the reclosing system by selecting manual or automatic mode, and may be sealed up to prevent tampering during maintenance work or once in operation.

Once installed, it has LED indicators to quickly, visually check its status (ON/triggered/reclosing) at all times.

To ensure full personal safety, the device is equipped with protective insulation, which deactivates the automatic reclosing system in the event of direct contact during handling, thus avoiding any injuries during start-up or maintenance work.

Its installation is really simple, since its compact size allows it to be fitted as a current circuit breaker, and the user does not need to make any type of connection between the circuit breaker and the motor, as it is completely built into its housing.

Maximum continuity, minimum space

FD REC4 espacio-en
 
The REC4 is a device designed for all those installations where service continuity is essential. As you will notice, there are many possible uses for Circutor's self-reclosing RCCB device, which is suitable for any type of electrical installation thanks to its compact dimensions.
Comfort at home

The REC4's functions make it particularly well-designed for domestic use, where most loads are single-phase. More and more devices operate autonomously and are controlled remotely. This is why RCCB tripping may cause several household problems.

FD REC4 vivienda1When we are away from home on holiday and the circuit breaker trips, the cables connecting electrical appliances such as fridges to the mains may become damaged, causing the contents of the fridge to get spoilt in a matter of hours. This problem causes economic losses in having to get rid of food and make us waste time cleaning it and switching it on again.

FD REC4 vivienda2Another example of the way the REC4 self-reclosing RCCB can be used is to prevent tripping from disconnecting the home's burglar alarm, leaving the premises unprotected against vandalism and theft. Installations such as air conditioning, lighting, garden irrigation or pool maintenance are also remotely controlled nowadays by mobile devices. The device will help us to keep them working at all times, avoiding surprises on arriving home or at our second residence, the latter being possibly the most important case for our self-reclosing RCCB device.

FD REC4 infra1

However, the advantages are not just restricted to guaranteeing constant functioning of household appliances when we are away from home. There will be numerous occasions on which we will appreciate the REC4 self-reclosing device, e.g. when the lights suddenly go out at home, sparing us the discomfort of moving in the dark to the mains panel to flip the switch.

Continuity in infrastructures

The main reason to equip infrastructures with the REC4 circuit breaker is to maximise single-phase load service continuity. The device will reclose almost instantly as long as there is no permanent leakage, avoiding shutdowns in different systems that lead to substantial economic losses which must be avoided at all costs.

FD REC4 infra2Wherever equipment is operating autonomously from a remote location, Circutor's self-reclosing RCCB will safely reclose in the event of protections tripping.

In the event of transient leakage tripping, the system will ensure that the installation continues to operate normally. On the other hand, if permanent leakage is really occurring, the system will try to reclose up to three times and if it the leakage persists, reclosing will not be completed, leaving the circuit open for a specialist to inspect it.

FD REC4 infra3For example, in the telecommunications industry it is very common to have different antennas spread over the country, with some of them located far away or inaccessible. A downtime in this type of infrastructure could lead to losses of around €30,000/min for the company, in addition to the cost and inconvenience of displacing personnel to the site to simply flip the switch.

Other examples along these lines would be public lighting installations, guaranteeing that the lighting system works in the city or on the roads, or the reclosing of low-cost petrol station facilities that do not have personnel on site to manually carry out reclosing. Instead of moving to locations to restore normal operation, the REC4 would restore the installation's proper functioning.

Smart charging points: the best option for your residential complex

on .

Electric vehicles are becoming more and more widespread, leading to the need for smart charging points to ensure operation. These charging points can be installed in a wide range of places, including the residential complex in which you live.

Where to charge an electric car

The electric vehicle has arrived, and is destined to play a major role in vehicle fleets in the not too distant future. Adaptation to this new type of vehicle must therefore start now. Just as with fuel-powered cars, electric cars need to be topped up. Charging points –which are becoming increasingly commonplace in cities– are therefore essential.

These points from which to charge your electric car can be located indoors or outdoors and can be either private top-up points or part of a public network. In this regard, an excellent option for your residential complex would be to install a smart charging point where sustainable vehicles can top up their batteries. You will be able to charge your vehicle every day without any problems.

What are smart charging systems?

What exactly are these systems? These charging points allow vehicles to be topped up efficiently. The system combines an electric charging unit with a series of parameters to ensure the vehicle’s battery is topped up at certain times of the day. It is a smart system, which charges batteries based on the cost of electricity throughout the day or at times of lower electric consumption in the building.

Furthermore, this smart charging system keeps track of which users top up their vehicles at the charging point and how quickly each electric vehicle must be charged. These points are ideal for charging your electric car.

Benefits of installing a charging point in your residential complex

You may ask what use a charging point is in your residential complex if there is already a public network. Public networks are not yet very widespread, meaning a top-up point such as this ensures your vehicle can be charged every night. In fact, by morning it will be fully charged and ready to use.

Moreover, the smart system is equipped with user identification to prevent unauthorised use. It should also be remembered that having a charging point in your residential complex will avoid the need to queue up and wait at public top-up points.

As you can see, electric vehicles are the future and require a place to recharge. Smart charging points are therefore an excellent idea in all residential complexes. Do not hesitate to contact us if you would like more information or advice.
