For which challenge in the high voltage market are you in need of a good transformer?
ELEQ transformers.

High voltage

Transformers for protection, measurement and revenue purposes. ELEQ transformers.

A high-voltage grid is a large network consisting out of high voltage electric conductors that is aimed at transporting large amounts of electrical energy over long distances. Electricity must be moved from the place where it is generated, to the site of the user. The network where the current can pass through is called the power grid. The high voltage must be transformed to a lower value, this happens in distribution stations. High-voltage energy transport has great advantages in terms of higher transport capacity as well as lower transport costs.

For more than 70 years now, ELEQ has been designing and manufacturing transformers for protection, measurement and revenue purposes. These transformers offer a compact, solid and safe solution. We offer standard as well as custom-made transformers for high voltage. Custom-made transformers and a quicker developing market urges for quicker innovations on our behalf. We are perfectly able to respond to this, as we have our own Product Development Centre (PDC) to count on, as well as on our own production.

Specific application in high voltage area

  • Electrical switching fields (hv)
  • HVDC
  • Power transformer station

Electrical switching fields (hv)

Energy needs measurement, protection and revenue metering (billing). ELEQ transformers.

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.

Within the power transformer the energy will be transformed to another energy level. Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes.

Process

From market and/or customer request to product

No matter what kind of questions you have, our specialized experts will surely find the correct solution for every particular situation. We consider each question as a challenge to arrive at the perfect result. Since we have our own Product Development Centre (PDC), this solution is more than just a rough drawing.

Within our PDC, we have an own designers team to prepare a detailed outline, a 3D printer allowing us to realise prototypes on the spot, a tool shop and a semi-finished products department. This allows us to be fully flexible to work out your solutions. At the semi-finished products department we are able to produce ourselves every screw or bolt needed for the solution. Besides, we also have an own extruding department. Next, we assemble the products by means of our automated manufacturing department. We also have testing devices, allowing us to test the products when needed before shipping them. From every transformer test reports could be consulted through our website. In short, our process from market and/or customer challenge to solution has become trusted within the electro-technical field thanks to ELEQ’s precision.
