Title:
REMOTE GROUND LINE MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP2017200407
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a remote ground line monitoring system capable of preventing a fault of a remote ground line monitoring device caused by a ground fault accident or the like by automatically connecting a remote ground line with a measurement part which measures ground resistance of the remote ground line, only in desired timing.SOLUTION: A remote ground line monitoring system comprises: a remote ground line monitoring device 2 for monitoring remote ground lines 52a and 52b connected with an earth potential rise maintenance device 51; and a management device 3 which is communicable with the remote ground line monitoring device 2. The remote ground line monitoring device 2 is accommodated in the earth potential rise maintenance device 51 and includes: a measurement part 5 for measuring ground resistance of the remote ground lines 52a and 52b; a connection part 6 for automatically connecting the remote ground lines 52a and 52b with the measurement part 5 only in desired timing; and a notice signal generation part 7 for generating a notice signal in a case where a measurement of the ground resistance measured by the measurement part 5 exceeds a preset setting. The management device 3 includes a warning generation part 10 which generates a warning in a case where the notice signal is received.SELECTED DRAWING: Figure 1
