Assessment of HYBRID GIS INSULATED SWITCHGEAR leakage

Assessment of HYBRID GIS INSULATED SWITCHGEAR leakage

2021-3-7Hybrid switchgear PASS (Plug and Switch System) encloses all functions of a complete switchgear bay in a single module. The hybrid design makes use of traditional air-insulated busbars to connect with other equipment in the substation while enclosing the following bay functions in a single-phase gas-insulated housing.
