Hawker Siddeley Horizon Breakers

Hawker Siddeley Horizon Breakers

(OP)
Hey Folks,

I am currently conducting a risk assessment on the installation of outdoor switchgear on a 22kV effectively-earthed system and on a 22kV non-effectively earthed system.  Towards this end, I am hoping to seek any information or experiences others have had relating to the performance history of Hawker Siddeley Horizon circuit breakers, and Whipp & Bourne type GVR reclosers.

Any assistance would be greatly appreciated.

Cheers,
flickstar
