5.6 Monitoring functions
5.6.1 Current transformer supervision
The current transformer supervision function (abbreviated CTS in this document) is used for monitoring
the CTs as well as the wirings between the device and the CT inputs for malfunctions and wire breaks.
An open CT circuit can generate dangerously high voltages into the CT secondary side, and
cause unintended activations of current balance monitoring functions.
