6.1.6.7 Negative-sequence overcurrent indication NSPTOC
Identification
Description
IEC 61850
identification
IEC 60617
identification
ANSI/IEEE C37.2
device number
Negative-sequence overcurrent
protection
NSPTOC I2> 46
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.
