Insights in energy usage in shops give information where energy flows. Depending on market requests, we offer various standard hardware possibilities for energy measurement purposes on the market. Please feel free to contact us and ask for the possibilities in case you are looking for a custom-made solution for energy measurement purposes.

The rotational movement of, for example, a windmill axis, is called mechanical energy. To convert this mechanical energy to electrical direct current, a generation is required. This transformation process in the generator is based on induction; this is a phenomenon that generates an electrical voltage when a conductor is situated in a changing magnetic field. A generator is often compared to a dynamo. A generator containing transformers can increase the voltage of the current, and thus the current can be transported over long distances with minimal loss.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes of generated energy.

A power plant is a large-scale industrial building where energy is generated. There is a distinction between power plants: some exclusively generate electricity, and some are thermal power stations, which generate both electricity and heat.The fuel is first burnt in a large incinerator. Loads of heat gets released, which is used to heat up giant amounts of water until steam formation takes place. The steam is heavily pressurised, and this pressure will then be used to drive one or more turbines. The turbine starts rotating and causes the generator to generate the current. Through this network of high-voltage pipelines, this generated power is transported to the consumers. Finally, the steam that drives the turbine is cooled off again in a heat exchanger, and the steam condenses back into water. The water is returned to the oven, and the circuit is closed again.

A large high-voltage grid where electrical power can go all directions is called a switching field. High voltage voltages of equal voltage can be connected to each other at a switching station where transformers are placed. All of these installations are switchable, and are also called electrical switching fields. Those fields makes it possible to redirect power and make maintenance work easier.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes within switching fields.

High voltage DC (HVDC) are voltages of 20 to 30 kilovolts. Today, there are hundreds of marine cable connections with HVDC and these work very reliable. HVDC is highly efficient for transmitting large amounts of electricity over long distances and special applications.

HVDC connections can either be landed or dug or sealed as sea cables. Direct current through these cables goes unlike the alternating current which goes through the entire mains. For long distances, alternating current is not suitable because of the risk of the shine effect, induction between the cables and also the influence of water. This water will provide additional resistance to the cable and can ultimately lead to heat development and unprofitable cables. This is why the direct current is used for very long distances. To transformer this direct current transformers are needed.

Power transformers are of great importance at any high voltage station. This transformer causes the electrical voltage to change in size, which in turn allows connections with varying power supply voltages. Power transformers are transformers connected to the high voltage grid, which have the ability to transform power of more than 10MVA. They are usually placed in a substation. Most of the time, there are three-phase transformers with an operating principle similar to the one of a regular transformer.

Power transformers can work on both sides, this all depends on what side the power is supplied to. For power transformers, the big advantage is the massively high efficiency. In the case of large power transformers, all electrical power that comes into it also comes out as electricity. It is a fact that efficiency increases with size; therefore large power transformers are also the most profitable.

At transformer stations, the electricity is transformed for either increasing or decreasing an alternating voltage. The energy generated in the power plant is transformed to a high voltage. At this high voltage, the energy goes through to the off-take points. There, the voltage is reduced again and led to transformer stations in, for example, residential areas.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes. Please feel free to contact us and ask for the possibilities in case you are looking for another solution for the transformation of energy.

A distribution station is provided with one or several transformers; it is a drive meant to convert medium voltage to low voltage. A distribution station is functional and essential for public energy supply services. The location cannot just be determined and has to meet predefined location criteria. They must also be easily accessible, with safe and efficient maintenance accessibility.

Today, we see an increase in their use; they are often included in buildings or underground objects. This puts less strain on public spaces and they have disappeared out of sight.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes.

An electrical switching field, also called switch bay, in a high voltage station consists out of many high voltage components. At a switch station, electrical power changes direction. A high voltage station also consists out of several switch bays such as transformer bays, line bays, coupling bays and generator bays. A switch bay consists out of several high voltage connections: power switches, separators that keep components separate in order to work without voltage, earth grounding, current meters and voltage meters. The remaining equipment for monitoring, controlling and security is housed in field houses in the switchyard. To change directions transformers are needed.
