Monitoring and Field Testing of High Voltage Metal Oxide Surge Arresters
Sažetak
The periodical control of MOA state is desirable, particularly of arresters placed in substations. The method for leakage current monitoring according to IEC60099-5 is preferable for control without elimination of voltage and disconnecting MOA. First experience of LSA monitoring in Croatia installed on 110 kV TL Ston-Komolac have shown that: - Monitoring system for wireless collecting data of LSA activity is useful system helpful in further analyses. - High surge activity and significant reduction of line outages.
