Hybrid Switchgear PASS M0H for H-configured substations – from 72.5 to 245 kV

Compact switchgear assembled and high-voltage tested switchyard for rapid installation and energization

PASS M0H belongs to Hitachi Energy innovative high-voltage hybrid switchgear family PASS (Plug and Switch System). PASS M0H encloses all functions of a complete switchyard in a single subassembly designed for connections to the high voltage network with an H configuration. On one side, it uses traditional air-insulated connections between equipment; on the other side, it encloses the selected 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 M0H module is completely factory assembled and tested, ready for rapid installation and energization.
