Summation current transformer
Total current transformers for primary nominal currents with 5 A or 1 A and a secondary nominal current of 5 A or 1 A (optionally 2 A) for the connection of 3 main transformers, in the accuracy classes 0.5 and 1.
Main converters with different gear ratios can be connected.
The respective nominal currents of the main converters must be specified when ordering (the ratio between the primary nominal current of a main converter and the sum of all main converter nominal currents may not exceed 1: 8).
