Summation current transformer – offsetting for tariff application
Summation current transformer for a primary nominal current of 5 A and a secondary nominal current of also 5 A for the connection of 3 main transformers, in the accuracy class 0.2, with type approval by the PTB Braunschweig for use for accounting purposes.
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).
