Low-Voltage Current Transformers

Low-voltage current transformers are designed for use in low-voltage distribution systems (with insulation voltage up to 750 V) with rated primary currents ranging from 1 to 3000 A.

The standard rated secondary current of the transformer is 5 A, although versions with a secondary current of 1 A can also be provided. Accuracy classes 0.5, 0.5S, 1, and 3 are intended for measurement circuits; these transformers have an overcurrent factor (n) of <5 or <10. Depending on specific customer requirements, transformers in higher accuracy classes (0.1, 0.2, 0.2S) or in accuracy classes 5P or 10P for protection circuits with a higher overcurrent factor can also be supplied.

ny pro obvody měření; tyto transformátory mají nadproudové číslo (n)<5, resp. <10. Podle konkrétního požadavku odběratele lze dodat i transformátory v lepších třídách přesnosti (0,1 - 0,2 - 0,2S) nebo v třídách přesnosti 5P či 10P pro obvody jištění s větším nadproudovým činitelem.
