Hybrid Switchgear PASS M0S - 245 kV

Compact switchgear fully assembled and high-voltage tested in factory

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.
