Current circuit supervision, current based (CTSU)

1.1

Application

Faulty information about current flows in a protected element might influence the security (line
differential protection) or dependability (line distance protection) of a complete protection sys-
tem.

The main purpose of the current circuit supervision function is to detect different faults in the
current secondary circuits and influence the operation of corresponding main protection func-
tions.

The signal can be configured to block different protection functions or initiate an alarm.

1.2

Functionality

The function compares the zero sequences currents, from the protection current transformer
core, with a reference zero sequence current, from another current transformer core. For exam-
ple from a measuring core.

The function issues an output signal when the difference is greater than the set value.
