Split-core transformer 333mV for energy saving

High energy costs, decentralised generation and energy agreements make energy saving a priority. ELEQ offers a variety of measurement solutions.

Changes are accelerating. Where you used to be able to look years ahead, it is now often difficult to plan a year ahead. The ever-increasing demand for energy, problems with the transport network, decentralized generation and the increasing demand for electric transport mean that the network design and (peak) consumption must be adjusted in the short term. In addition, the grid is more polluted by decentralized generation and today’s equipment is more sensitive to this pollution, which can cause disruptions.

Smart automation

Smart energy monitoring offers the solution to optimize energy consumption. Think, for example, of making it possible to read and control energy consumption locally and remotely. To achieve this, ELEQ has developed a complete energy management line with current and voltage transformers.

Transformers with a 333mV output

Because measurements often have to be done in existing situations, ELEQ has developed both very small current transformers (RM17 and RM27) and split-core transformers (TQ line). This line has now been expanded with products with a low voltage output, such as 333mV. The advantages of a low voltage output are that they are safer and easy to install:

The transformer does no longer needs to be short-circuited.
There is less cable loss, which means that much longer and thinner cables can be used.
Thinners cables offer the opportunity to be manufactured with, for example, RJ plugs.

In short, ELEQ offers the solution for proper measurement in smarter energy monitoring.

ELEQ Smart City solutions

ELEQ Smart Multi Connection Box and Application Modules

A smart city is a city that uses advanced technology and data analytics to improve the quality of life for its residents and enhance the sustainability of its infrastructure. Making a city accessible and liveable is an important challenge for the future. How do we shape the energy transition and how do we keep our infrastructure efficient and available? Technology and digitization play a major role in managing this large-scale change. The goal of a ‘Smart City’ is simply to increase the quality of life of its residents and visitors. This requires smart solutions and the right technology. That is what ELEQ offers.

The reuse of existing objects in private and public space is the most sustainable solution and prevents a proliferation of lampposts, communication masts and EV charging stations. Due to their height and existing infrastructure – in combination with smart solutions from ELEQ – light poles are extremely suitable for social tasks such as improving mobility, efficient energy use, health and safety.

Mobility

One of the key areas of focus for smart cities is transportation. Smart cities use data from sensors and connected devices to optimize traffic flow, reduce congestion, and improve public transportation. This can include intelligent traffic management systems, real-time transit updates, EV charging facilities, load balancing, and smart parking systems that guide drivers to available spots. By making transportation more efficient, smart cities can not only reduce traffic-related emissions but also improve air quality.

Energy efficiency

Another important area for smart cities is energy efficiency. Smart cities use sensors and data analysis to optimize energy usage, reduce waste, and improve sustainability. This can include smart lighting systems that automatically adjust the amount of light based on occupancy, weather, and time of day, but also smart buildings that use energy-efficient materials and sensors to monitor and adjust heating and cooling systems. To ensure optimal operation of these and other new functionalities, ELEQ has developed the Smart Multi Connection Box including a compact kWh meter and communication module. By improving energy efficiency, smart cities can reduce their carbon footprint and save money on energy costs.

Public safety and security

A smart and connected society starts with high-speed internet. Not only at home or at work, but also outside the house. Safety and security is ensured by connected devices and sensors monitoring public spaces, tracking crime trends, and improving emergency response times. This can include things like CCTV cameras, sound detection systems, and predictive policing algorithms. The Connection Box Fiber from ELEQ offers real-time transfer of large files, allowing you to make optimal use of camera applications or traffic installations. In combination with a sound sensor this offers a solution to quickly give warning by incidents, map out the daily noise, monitor temporary situations and measure how many decibels of noise pollute the public space.

ELEQ opens unique Public Connection LAB

The public area is evolving fast. And ELEQ and fellow suppliers are keen to provide solutions to support those developments. Last Thursday, our local councillor opened ELEQ’s Public Connection LAB, which will enable the in-house testing of new connection boxes and connection box applications.

In the LAB, we test our connection boxes and work with fellow suppliers to run scenarios involving public lighting, electric charging and electric street furniture, such as testing and connecting a new intelligent lighting system using ELEQ’s connection boxes.

We are currently testing the possibility of using lamp posts to charge electric cars, and the tests are going well. At the time of opening, there are already three charging points available in the LAB which ELEQ visitors can use to charge their cars during their visit. The charging stations are, of course, supplied with ELEQ connection boxes!

If you have an idea for a scenario that you feel needs testing, let us know! Send an email to [email protected] or call Wim van Turennout at +31 6 203 654 94.

ELEQ 333 mV Transformers for smart station automation

The energy market is constantly in motion. Where grid operators used to plan changes for the long-term, the energy transition is forcing a rapid redesign of the grid. An example of this is the uptake of solar panels in certain districts, which affects the required grid capacity. The grid is also becoming destabilised by decentralised generation, and modern equipment is more sensitive to that instability, which can cause disturbances.

Smart station automation

Smarter station automation offers a solution for monitoring grid performance properly. For example, this could include options for local and remote reading and station control. Relevant data to monitor include current, voltage, power, temperature and humidity, short-circuit and overload. When unusual activity is detected, the station can be remotely switched off or diverted.

Transformers with 333 mV output

Correct measurement is the foundation for smarter station automation. To that end, ELEQ offers a range of transformers with 333 mV output. In addition to our split-core current transformers (TQ), we are developing our smallest transformers, the RM17 and RM27, with a voltage output.

The benefits of our 333 mV range are:

Easy to install
- o The TQ transformers are split-core, which is also perfect for retrofit jobs;
- o Longer cables possible to the measuring unit.
Safe
- o The transformer does not need to be short-circuited when the meter has to be disassembled.

In short, ELEQ offers the solution for correct measurement to enable smarter station automation, working together with leading international companies to achieve it.

Seventy-five years after the family business ELEQ was founded, we can now welcome a fourth-generation Getreuer. In joining the business, Reinout Getreuer is following in the footsteps of both his father and his great and great-great grandfathers.

ELEQ can trace its origin back to 1946, when the company began the small-scale manufacture of ingenious and robust measuring instruments. “On his 23rd birthday, helped by my great-grandfather, my grandfather, Edgar, with a friend, founded his own company, says Reinout.

From day one, pinpoint precision has been our creed. Precision which gradually came to be valued by an increasing number of markets. Growth in knowledge of products and areas of application and rising demand led to a constant growth in scale.

“In 1983, my father, Robert, joined the business”, says Reinout, “after which there was period which saw continued growth and globalisation, and the business name change to ELEQ.”

ELEQ currently offers a wide product range of reliable transformers, smart converters, accurate meters and connection boxes for the energy market, including standard products and bespoke products for many national and international customers, large and small. Reinout: “Making bespoke products for customs is in ELEQ’s DNA. This was already evident in the way Edgar ran the business, and is no less apparent in Robert’s case; this is where we see passion behind management’s efforts to meet the challenges posed by customers with the perfect electrical solution.“

This approach ties in perfectly with the energy market, a dynamic market which is changing fast, and precisely at a time when there is ever more demand for more innovative solutions ELEQ is a dynamic organisation which intends to be ready for tomorrow’s markets through today’s innovations. Reinout is keen to take up the challenge: “The electrical energy sector represents the biggest system transition since it first came into being in the 19th century. This transition is a challenge which will require a huge amount of innovation. Let’s make sure we are a key part of that change! A change that will come to pass only if we pull together.”

Since its foundation, ELEQ has stood for craftsmanship and expertise in electrical applications. Craftsmanship and expertise we are able to provide thanks to the efforts of our employees. Reinout: “For us, good business practice means treating people, society and the world with respect. That’s why, notwithstanding our international customers, we have forged close links with those close to us, in part so that we can foster the well-being of our employees.”

ELEQ Voltage Transformer for decentralised generation

As synergy results in energy we aim for partnerships. One such example is the metering challenges presented by high voltages in decentralised generation. In this case, ELEQ collaborated with wind turbine builders, energy companies and panel builders to develop a line of voltage transformers. The new transformers allow the continued use of standard kWh meters for both the metered voltage and the supply voltage.

Together with our customers we came up with a solution for the challenge. The challenge was:
– High voltages in decentralised generation prevented the use of standard kWh meters.

While working closely together we developed a voltage transformer that allows the use of standard kWh meters for both the voltage to be measured and the supply voltage. This has the following advantages:
– Simplified installation;
– Cost savings;
– The transformers satisfy the standards for metering.

Craftsmanship and expertise

For more than 70 years ELEQ has been offering craftsmanship and expertise in electrotechnical applications. We do not only use this gathered knowledge to work continuously together with customers on new products, innovations and smart solutions, but also by participating in research.

Recently PAC World Magazine published a study where our engineer Douwe Baars contributed to together with ABB. The subject of this study is the influence of an external magnetic field on a ring-core Current Transformer which can, for example, be applied in power transformers or switchgear.

In short the study stated that under certain conditions an external magnetic field is able to saturate the core of a ring core current transformer locally. A significant peak current can be generated by the secondary winding at the instant of switching on an external magnetic field, e.g. due to the asymmetrical inrush current of a power transformer. This undesired peak current might trip the protection system. A winding for flux compensation can prevent this peak current almost completely.
