PASS M0S belongs to Hitachi Energy’s innovative high-voltage hybrid switchgear family PASS (Plug and Switch System). PASS 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:
- Circuit breaker
- Combined disconnector and earthing switches
- Voltage transformers and Voltage sensors
- Current Transformers
- Motor drive option
- Fast earthing switch option
- Plug in cables option
PASS modules are completely factory assembled and tested, ready for rapid installation and energization.
