The NPG Mining PFSR-1kV Phase Failure & Phase Sequence Relay built by Electronet has been designed to reduce the risk of damage to equipment due to the incorrect phase sequence being applied to the electric motors & driven equipment e.g. Hydraulic Pump.
The relay has been designed with internal fuse protection and to operate direct off 1000V.
This feature eliminates the use of a step down transformer, providing a significant space saving and ease of connection.
