The arrester run monitor
1 Purpose and classification
Arrester monitor (hereinafter referred to as the monitor) is connected in series in the arrester low-voltage side, used to monitor the arrester leakage current changes and action times, and reported to a device. Applies to the operation and monitoring of the power system a variety of voltage levels of zinc oxide surge arresters, the silicon carbide arrester. Arrester line monitoring with discharge counter
Monitor Category:
According to their use of objects can be divided into: two porcelain shell or polymer housed surge arresters and GIS tank arrester.
According to their supporting arrester system nominal voltage can be divided into: 35kV, 110kV, 220kV, 330kV, 500kV, 750kV, 1000kV.
