Abstract
Apparatus for preventing energy leakage from a transmission line treats the line as a “partially closed” vessel. A gas stream with a pressure slightly different from ambient pressure is provided to the interior of the transmission line and a conduit that allows gas to pass between the transmission line and the ambient environment is provided. The gas flow rate at the conduit is then detected and monitored. If the flow rate falls outside a predetermined threshold, an electrical energy leakage is indicated. In another embodiment, the pressure of the input gas to the transmission line is continuously checked by a pressure switch, which will detect a change in pressure if the transmission integrity is compromised and disable the energy source.
