Negative-sequence overcurrent indication NSPTOC

Identification
Description
Negative-sequence overcurrent
protection
Functionality
The negative-sequence overcurrent protection function NSPTOC is used to increase
sensitivity to detect single-phase and phase-to-phase faults or unbalanced loads due
to, for example, broken conductors or unsymmetrical feeder voltages.
