Abstract :
This paper reviews the principles of ground differential protection within industrial power systems and discusses the use of directional overcurrent relays in this application. Electromechanical product type relays have been the device used primarily for this application. The use of current polarized directional ground-overcurrent relays provides a novel approach in the application of ground differential protection
