Protection & Interlocking Systems.
  • Protection tripping events need careful management in automated networks and switchgear, Weirgrove's network management systems are programmed to recover sections of networks or busbars while inhibiting unsafe switching practices.
  • Protection and interlock status contacts are also normally included in hardwired interlock schemes to prevent unsafe switching in manual operating modes.

  • Protection design studies and calculations.
  • LV and MV Protection Systems in switchgear packages.
  • Managed G59/2 mains paralleling generator protection schemes.
  • Self healing redundant ring distribution systems with fault passage detection.
  • Grading and blocking schemes.
  • Injection testing and validation on site.
  • Robust hardwired interlocking schemes, state stable and failsafe.
  • Boolean logic configured in intelligent protection relays.
  • Modbus communications and integration with monitoring by Weirgrove control systems and HMIs.
