6.6 PROTECTION FUNCTIONS

6.1 OVERCURRENT 50/51/50N/51N

6.1.1 DESCRIPTION

Functions 50/51/50N/51N are meant to protect the line against overloads and shortcircuits.

The 50/50N functions are protections against shortcircuits between phases (50) or phases and neutral
(50N). This is done by an instantaneous breaking command when the current is above a configurable
threshold.

The   51/51N   functions   are   protections   against   overloads   between   phases   (51)   or   phase-neutral
overcurrents (51N). This is done by a timed breaking command, configurable as a timer or a current-
dependent timer.
