Zusammenfassung:	PCT No. PCT/FR93/01000 Sec. 371 Date Apr. 19, 1995 Sec. 102(e) Date Apr. 19, 1995 PCT Filed Oct. 8, 1993 PCT Pub. No. WO94/10735 PCT Pub. Date May 11, 1994A method and a device for measuring compensation balance and imbalance in an electrical supply network having a balancing coil. An auxiliary measurement signal is injected into the network's neutral circuit, changes in the homopolar voltage induced by the auxiliary signal injection are measured, and an impedance measurement is obtained by comparing the changes in the hompolar voltage with the injected auxiliary measurement signal, in terms of both amplitude and phase. A parallel current may advantageously be injected into the neutral circuit at the secondary winding of a homopolar transformer placed in the neutral coil.
