Reactive energy compensators

A few more explanations

Reactive energy compensation: a high-return investment that helps combat the greenhouse effect.


To operate a machine, you use a motor, which means you consume electrical energy. In electrical engineering, this energy is called active energy.

For this motor to work, a magnetic field has to be generated, and to create it, a current is needed, which we call reactive. This generates reactive energy.

This reactive current, distributed by the power station, will generate the reactive energy that clogs up the network.

To compensate for the reactive energy, we need to reduce or eliminate the losses produced by circulation in the network.

By compensating for reactive energy, we prevent some or all of it from circulating in the network, which results in a reduction in current.

This is where the electrical capacitor comes in, supplying the reactive power needed by the motor without going through the power station. In fact, the delivery of reactive energy by the power station leads to an increase in the current delivered and therefore an increase in the EDF bill.

When correctly sized, the capacitor can supply the necessary reactive energy without using the energy generated by the power station.

The user therefore has two options:

- Optimise your contract by reducing the contract power.

- Access additional power without changing your contract.

The environmental component is also very strong, since the reactive energy compensator makes it possible to significantly reduce CO2 emissions, thereby reducing greenhouse gas emissions.
