Abstract :
Plenty of electronic equipment is now being served as part of microcomputer protection and integrated automation system in substation. However, ground potential arise caused by lightning current or current at industrial frequency crossing by grounding grid will produce voltage on transmission line, which can therefore disturb certain secondary equipment. This paper summarize some disciplinary conclusion by measurement.
