GIS leak rate for Siemens

GIS leak rate for Siemens

May 25, 2020The leakage rate is extremely low, less than 0.1 % per year. HV switchgear (< 52 kV) use closed pressure systems with leakage rates less than 0.5 %, which is the maximum permitted by the relevant IEC standards. The operating pressure of HV equipment is approx. 5 times higher compared to MV. 11.
