Ground Fault Protection

Introduction

A ground fault is the shorting of an electrical device or circuit to ground at any location other than the structure's common grounding electrode. This can be caused by damaged or faulty wiring, or by the installation of a second grounding electrode. In order for your system to be protected, if a ground fault exists it is highly recommended that your ground fault is quickly isolated from the system to prevent serious damages. The used of ground fault protection relays is one of the best way to indicate and isolate a ground fault.
