Table of Contents

Overview

Open or short circuited current transformer cores can cause unwanted operation of many protection functions such as differential, earth-fault current and negative-sequence current functions. “Current circuit supervision (CCSSPVC)” function compares the residual current from a three phase set of current transformer cores with the neutral point current on a separate input taken from another set of cores on the current transformer.

For more detailed information on “Current circuit supervision (CCSSPVC)” function, refer to ABB, Relion 670 Series manuals.
