Ground-Fault Protective Scheme For Multiple-Source Electric Distribution System

US Patent:
3949272, Apr 6, 1976
Filed:
Nov 19, 1974
Appl. No.:
5/525150
Inventors:
Eugene M. Smith - West Chester PA
Assignee:
General Electric Company - New York NY
International Classification:
H02H 328
US Classification:
317 18D
Abstract:
A ground-fault protective scheme for a three-phase electric distribution system that comprises two sources having neutral points that are interconnected by a neutral conductor and a separate ground connection for each neutral point located at or near the neutral point. The protective scheme responds correctly to a ground fault even though the current resulting from such ground fault may return to its source through either of said ground connections and may distribute itself in any proportion between said ground connections.
