Zusammenfassung:A large 34.5-kv system was operated ungrounded until early in 1946, at which time resonant grounding was installed, since it promised to be the most effective and most economical method of improving reliability of service. The layout of the system and a description of tests with the groundfault neutralizer installed are given. Records ords of operation indicate that the improvements gained by resonant neutral grounding are considerable and fully in line with expectations.
