Method and device for measuring the agreement and the disagreement of compensation of an electrical distribution network.

摘要

Method for measuring the tuning and disagreement of the compensation of an electrical distribution network comprising a compensation coil (1), characterized in that an auxiliary measurement signal is injected into the neutral circuit of the network, in that the variation in the zero sequence voltage induced by said injection of the auxiliary signal is measured and in that an impedance measurement is carried out by comparison, in amplitude and in phase, of the variation in the zero sequence voltage with the injected auxiliary measurement signal. Advantageously, a current is injected in parallel into the circuit from the neutral to the secondary of a homopolar transformer placed in the neutral coil.
