| Abstract: | According to the request of anti-accident technical measures in electric power system secondary circuit, this paper carried on theoretical analysis and computation for abnormal connection of secondary circuit in 500kV line PT, concluded its influence to electric power system relay protection and thereby proposed corresponding countermeasures. At the same time, focusing on grounding of secondary circuit, it is meaningful to correctly carry out anti-accident measures of relay protection and automatic safety device. |
