This project involved the installation of a total of 151 sensors at a 110kV substation in Fujian Province. The deployment included 38 ultra-high frequency (UHF) sensors, 113 3-in-1 partial discharge sensors, 3 high-frequency current sensors (HFCT), and 23 data concentrators.
During the monitoring process, partial discharge activity was detected in the 110kV GIS disconnector. The discharge was identified as corona discharge.
