Hybrid Switchgear PASS M0S - 420 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 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

• Optional:
  - Fast earthing switch
  - Cable terminations

PASS modules are completely factory assembled and tested, ready for rapid installation and energization. This is achieved by providing a simple, safe and effective tool to rotate bushings from service to transport position. A robust sealing interface ensures tightness during and after rotations.

• Integration of renewables power to the grid

• Remote mining connections

• Mobile or skid mounted substations

• Substation extensions or bay replacements

• PASS is the most widely installed hybrid switchgear worldwide, protecting networks in many different climates and applications

• Delivered fully assembled and tested, allowing energization within 24 hours for a single busbar configuration

• Modular design enables highly customizable solutions in a short manufacturing time

• Global service organization to support the equipment in operation through its entire lifetime
