Description
The phase sequence and phase failure protector trip relay is designed to monitor
the correct phase rotation or sequence of a three-phase supply system. It provides
protection against incorrect phase sequence, loss of one phase and under voltage.
Two versions are available to suit either three-phase three-wire (PVR3) or threephase
four-wire (PVR4) systems.
