Full Description

Scope

This guide has been prepared to aid in the application of relays and relaying schemes for protection against stator ground faults on high-impedance grounded generators. The guide is not intended for the selection of generator or ground connection schemes. Differential relaying will not detect stator ground faults on high-impedance grounded generators. The high impedance normally limits the fault current to levels considerably below the best practical sensitivity of the differential relaying. Separate ground fault protection is then provided.

Abstract

Revision Standard - Superseded.Superseded by IEEE Std C37.101-2006. Guidance in the application of relays and relaying schemes for protection against stator ground faults on high-impedance grounded generators is provided.
