直流回路一点接地引起监控误报警原因分析及对策

Reason Analysis on the Error Alam Caused by the Single-point Grouding of DC Circuit

深入分析了直流回路一点接地引起两种不同开关量输入方式的测控装置误报告警信号的原因,提出了应对这种故障的有效措施。

DC-depth analysis of this paper that the single-point grounding of DC circuit caused by two different modes of switch Input alarm signal monitoring device of the reasons for false positives,a response to this failure of effective measures.
