The balancer is intended for use in a power supply unit to permit improvement of the balance in an electrical three-phase system, whereby the balancer functions for example as a filter and, when used in a measurement apparatus, to permit the formation of a stable reference point with regard to the amplitude, phase and frequency of electrical quantities in a three-phase system. The balancer is characterised specifically in that, for each phase in the three-phase system, it comprises a separate toroidal magnetic core (12, 14 and 16), on which are arranged at least two mutually electrically isolated windings (18, 20; 22, 24; and 26, 28), which are Z-connected. |
