UMG 508Connection diagram for currentmeasurementYou can select between the following connectiondiagrams for current measurement:3p4w3p5w3p2i3p2i01p2i- 3 phase 4 conductor, 3 current conv.- 3 phase 4 conductor, 4 current conv.The fourth current transformer can beused for measuring the neutralconductor e.g.- 3 phase 4 conductor, 2 current conv.For networks under symmetric load.- 3 phase 3 conductor, 2 current conv.Aron connection for networks withouta neutral conductor. The third currentwill be calculated.- 1 Phasen 2 Leiter, 2 StromwandlerFactory pre-setting: 3p4wCA connection diagram does not haveto be configured for measurement inputsV4 and I4.Illu. Example for current measurement using 3current converters in a 3 phase 4 conductor network.53
