Abstract
A reactive power compensator for a three-phase network having first, second and third phases includes an assembly of capacitors and electromechanical contactors electrically connected to the capacitors. Each contactor includes at least one upstream and one downstream power terminal. An electric current circulates between the upstream and downstream power terminals when the contactors are closed. A first contactor is connected to the first phase and a second contactor is connected to the third phase. The voltage between the upstream and downstream power terminals of at least one electromechanical contactor is measured so that the electromechanical contactors can be controlled according to a control algorithm. The control algorithm includes the closure of a contactor for a substantially zero voltage between the upstream and downstream power terminals thereof, and the opening a contactor for a substantially minimum power value of the capacitors to which the contactor is connected.
