How to pinpoint insulating gas leaks quickly without the need to de

The insulating gas was found to be leaking from the control cable conduit into the control box. The leak had originated on the 275kV breaker, with SF 6 building up in the control box at the breaker and being forced down the cable conduit to where it picked up by the camera. GasVue easily detected the leak and pinpointed its exact origin.
