Figure. 5.5.1 - 120. Simplified function block diagram of the CTS function.

Measured input

The function block uses analog current measurement values, the RMS magnitude of the current

measurement inputs, and the calculated positive and negative sequence currents. The user can select

what is used for the residual current measurement: nothing, the I01 RMS measurement, or the I02

RMS measurement.
