A precise ultra high frequency partial discharge location method for switchgear based on received signal strength ranging

International Journal of Distributed Sensor Networks, 2020
Partial discharges are the main insulation defects encountered in gas-insulated switchgears. When it occurs inside the gas-insulated switchgear cavity, it degrades insulation, and, sooner or later, causes a breakdown.
