发明名称 Förfarande och anordning för att mäta kompensationsbalans och obalans i ett elmatningsnät
摘要 <p>Method of measuring the match and mismatch of compensation of an electrical distribution network, including a compensation coil (1), characterised in that an auxiliary measurement signal is injected into the circuit of the neutral of the network, in that the variation in the homopolar voltage induced by the said auxiliary signal injection is measured, and in that a measurement of the impedance is taken by comparison, in amplitude and in phase, of the variation of the homopolar voltage with the auxiliary measurement signal injected. Advantageously, a current is injected in parallel into the circuit of the neutral at the secondary of a homopolar transformer placed in the neutral coil. <IMAGE></p>
