Hybrid Switchgear PASS M0S - 245 kV

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 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
• Current Transformers
• Optional:
  - Voltage transformers
  - Fast earthing switch
  - Cable terminations

PASS modules are completely factory assembled and tested, ready for rapid installation and energization.
