Total flexibility for any installation

The Line devices which are part of the integral Energy Management System (EMSi) offers multiple combinations, allowing you to create a solution custom-made for each installation.

Easy installation

The modular design of the system allows any associated Line device to be installed quickly, securely and automatically thanks to its integrated Bus-Line communications.

This protects against alternating sinusoidal currents, applied both suddenly as well as smoothly and progressively.

Although it’s prohibited in some countries in the European Union, in Spain its use is mainly extended to the domestic level, where more basic loads predominate.

This one deals with the same cases as the AC type and also includes:

• Protection for direct pulsating currents
• Protection for direct pulsating currents superimposed on a continuous earth leakage current of up to 6 mA

These are applied with or without angle control, regardless of polarity, that may appear both suddenly as well as smoothly and progressively.

It’s the commonest protection type in industrial settings and, in some parts of Europe, it’s also compulsory for domestic use.

This covers the scenarios included in type A (remembering that type AC has already been mentioned) and it also provides:

• Protection for composite earth leakage alternating currents (including wave composition with frequencies of 1 kHz), appearing both suddenly as well as smoothly and progressively, intended for circuits powered between phase and neutral or phase and the grounded middle conductor.
• Protection for alternating earth leakage currents superimposed on a smoothed direct current (mixed current).

These types of earth leakage are the least commonly used; they are mostly used in special single-phase applications.

It deals with the scenarios for type F (that is, type AC + type A) and also provides:

• Protection for sinusoidal differential currents up to 1000 Hz
• Protection for alternating earth leakage currents superimposed on smoothed direct currents up to 0.4 times the nominal sensitivity of the protection device or up to 10 mA (whichever is higher)
• Protection for smoothed continuous earth leakage currents.
• Protection for pure continuous earth leakage currents that may arise from correcting electrical circuits (for example, 3 or 6 pulse bridge connections) that are applied with or without angle control, regardless of polarity, that appear both suddenly as well as smoothly and progressively.

This is the most complete type of protection. It guarantees the measurement and protection against loads of alternating current, pulsating current or pure direct current.

Industry: Variable speed drives, used in countless different processes, such as conveyor belts, air conditioning, pumps, cranes, elevators of any kind, etc. In short, any process that requires a variable speed movement to carry out its function. What motor does not incorporate a drive nowadays?

Offices: UPSs for data protection centres

EV charging: EV charging points. Photovoltaics

Equipment with power electronics, Inverters, Harmonic filtering (active filter), etc.

In Spain the Low Voltage electrotechnical regulation (REBT 2002) establishes in ITC-BT-24 (Spanish) the obligation to protect the installation against direct and indirect contacts for installations with type TT earth connection plans (all the mass of the electrical equipment and the neutral of the transformer on the same earth).

However, except for ITC-BT-52 (Official State Bulletin No. 316), which is specifically for EV recharging points and where it is established that the protection will be type B or type A with a supplementary protection for continuous currents of values greater than 6 mA, the regulation does not establish any advice or criteria for selecting the type of earth leakage in our facility.

So, how do I choose for other cases?

We’ve already shown that the type of earth leakage dictates the type of loads it protects from, based on its response. It makes sense, therefore, to bear in mind that each load will use a type of earth leakage protection based on the type of earth leakage it can present.

IEC 60755 standard sets out the general requirements for residual current devices. It establishes the different types of leakage in relation to the different types of charges.

Nobody understands the way loads respond better than the manufacturer itself.

Therefore, when we select a type of earth leakage protection, we must consult the load manuals containing instructions on how to manage its correct protection. Otherwise, in the event of an equipment malfunction, or worse, in the event of an electrical incident due to human error, by not following the manufacturer's instructions, the responsibility for misuse will obviously rest with the end user.

The most reputable manufacturers of drives, UPSs, electric vehicle recharging units, active filters, etc. specify in the section on installation recommendations or warnings the correct load protection and for avoiding untimely trips, the earth leakage protection to be installed must be TYPE B.

Compatibility with RCCBs.
If you are installing an earth leakage protection device (RCD), the frequency converter will function without unwanted tripping and will provide adequate protection whenever a type B earth leakage device is used

We have seen that in order to select the type of earth leakage protection we need, we must look at the load response. However, when we install earth leakage devices in series, upstream of the charge, what selection criteria should we use?

This is what is known as vertical selectivity. The correct selection of the characteristics of the earth leakage devices in series, from the beginning of the charge, through the set of charges (sub-frames) and reaching the protection of the mains panels, should not only take into account the type of charge, but also we must consider other aspects that will indicate the correct coordination of the protection system.

These 3 conditions must always be met in vertical selectivity:

• Ammeter: The sensitivity of an earth leakage must be at least 3 times the sensitivity of the earth leakage device installed downstream.
• Chronometric: The time response of an earth leakage device must be at least twice the maximum time of the earth leakage device installed downstream.
• Type: The earth leakage must be of the same type or higher than the earth leakage device installed downstream

Thus, for vertical coordination of types of earth leakage device, the following table may be helpful:

Therefore, whenever we protect a load with type B protection, all the protection that is in series upstream (subframes, general earth leakage protection) must also be type B

Given the growing requirement of users to cover protections of this type of charge, CIRCUTOR has a wide range of type B earth leakage protection solutions.

IDB-4: 4-pole type B RCCB for three-phase and single-phase installations up to 63 A. Sensitivity of 30 or 300 mA (direct earth leakage device), instantaneous trip time.

WGB-35-TB: Earth leakage relay with transformer included (MRCD), for loads up to 125 A. Sensitivities of 30 or 300 mA, instantaneous or selective trip time.

RGU-10B: Earth leakage relay associated with transformers of the WGC-TB (MRCD) range, up to 180 mm internal diameter, allowing protection of charges of up to 800 A. Sensitivity from 100 mA, programmable trip time.

RGU-100B: Earth leakage relay associated with transformers of the WGB (MRCD) range, up to 110 mm internal diameter, allowing protection of loads of up to 400 A. Sensitivity from 30 mA, instantaneous and programmable trip time.

CBS-400B: Earth leakage relay associated with transformers of the WGB (MRCD) range, up to 110 mm internal diameter, allowing protection of loads of up to 400 A. Sensitivity from 30 mA. With 4 channels for the protection of 4 totally independent circuits. Instantaneous and programmable trip time.

RECB: 4-pole type B RCCB with automatic reclosing for three-phase and single-phase installations up to 63 A. Sensitivity of 30 or 300 mA (direct differential device). Instantaneous trip time.

We have seen how the different types of earth leakage devices (AC, A, F and B) are defined, according to international framework regulations, and according to the type of leakage they protect against. In other words: the type of earth leakage device is intrinsically linked to the operation and technology of the load to be protected.

It is therefore essential, for the correct selection of the type of earth leakage device, to know what response it has and how the load to be protected works. Manufacturers of the loads, in their manuals and advice, will indicate the approach to take and how to make the selection.

It is equally important to respect all vertical selectivity conditions for the correct coordination of our protection upstream of the charge and at the head of the installation, also respecting the type of earth leakage device.

With these basic guidelines, we will not only ensure maximum continuity of service to preserve the protection of the charges and assets of our facility, but we will also guarantee the safety of individuals.

• By Bluetooth using the MyConfig app.
  You don't need to carry a computer to the facility to set the IP address and leave the analyzer connected to the LAN.

• By web page via Wi-Fi or Ethernet.
  Connect to the analyzer through a web server and easily configure all its parameters from your own computer if you are connected to the same LAN. Use any browser to program its IP and other communication settings.

• By using its display
  Programs the communications of the device directly through its display. Once configured you can check the IP and parameters set as well as the level of Wi-Fi coverage if you are connecting wirelessly.

Voltage & current phase connection error

The voltage wiring must correspond to the current wiring of the same phase. If this does not happen, it means that the installation has been performed incorrectly. This will cause values such as power, cos phi, PF or energies to be incorrect.

Error installing current sensors

The installation of the current transformers must be correct, following the flow direction of the load. If a transformer is installed reversed, the current will be displayed as generated current instead of consumed or vice versa, having an error in the total energy register.

We believe that this is a radical change in mobility, but really the first electric cars already appeared in the early nineteenth century (1832/1839). At the time there were already rumours about cars that made no sound and emitted no smell (in the same way combustion cars would have been at the time) and there was already talk of the importance of autonomy. At the beginning of the 20th century these cars evolved to be able to travel distances greater than 100 miles.

However, at the same time Colonel Drake appeared on the scene with his oil wells in the United States, and also Henry Ford with his Ford T, the first combustion car made on an assembly line, and the first great battle between the electric car and the combustion car was won by the latter.

But now, in the 21st century, the situation is very different. The problem with fossil fuels, worldwide legislation promoting electric mobility (Europe has implemented “aggressive” regulations to reduce the greenhouse effect in order to comply with the Paris Climate Agreement) and, above all, the serious problems associated with pollution worldwide, make the electric vehicle a key element in the transformation of society towards a more responsible attitude and awareness of environmental issues.

When thinking of potential future users of electric vehicles, there are two major concerns: firstly, the cost of an EV and secondly, the availability of charging points on public roads, known as emergency recharging.

Recently, Erik Jonnaert, the secretary general of ACEA, (European Association of Automobile Manufacturers) published an article in which he explained that the automobile sector is experiencing one of the greatest periods of transformation in its history, which will mean that “in three years’ time, an electric car will cost a similar amount to a conventional car.”

Regarding the availability of charging points on public roads, an article has been published, which refers to the fact that there are currently 100,000 charging points in the European Union and it is expected that by 2025 this figure will multiply by 20 until it achieves 2 million stations.

To contribute towards achieving this objective, Circutor, a Spanish company and pioneer at a European level, has been working over the last ten years to offer recharging solutions for each of the requirements that electric vehicle users may have, both on public roads with direct current equipment (rapid charge), as well as in private use (linked charge) with alternating current equipment (slow charge).

LINKED RECHARGE

This is a slower charge, using alternating current (from 3.7 kW to 22 kW Circutor eHome and eNext models), which connects to you car’s parking space. The main objective of this way of charging is to take advantage of the night-time hours when most people have their car parked, charging it in 6 to 8 hours, during which time the power required can be released from our home at night and can be obtained at a very low-cost electricity rate.

ON-STREET RECHARGING

On public roads there are two types of solutions, the semi-rapid one which can be found in shopping centres and hotels. This would use an alternating current recharge with a maximum power of 22 kW (URBAN model by Circutor).

The second solution is the faster one and is designed for service stations that offer electric recharging, these are known as electricity stations. For these, recharging is carried out with direct current (50/150 kW Circutor's Raption Model), and the time required must be as short as possible, not more than 30 minutes.

The combination and implementation of the different recharging types begin to guarantee the user the ability to travel in Electric Vehicles with the same promise of autonomy that combustion vehicles offer today, but while enjoying a whole new driving experience, and most importantly respecting the environment and building a sustainable future for the generations to come.

The imminent deployment of charging points, in combination with commitments from large automobile manufacturers as well as growing public awareness, leave no doubt in our minds and allow us to vouch wholeheartedly that the Electric Vehicle is not a passing fashion or trend, but it is a reality and a global commitment, which will radically change, and is already changing, our current mobility model.
