<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for preventing energy leakage from electrical transmission lines. <P>SOLUTION: The apparatus for preventing energy leakage from a transmission line treats the transmission 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, and the pressure switch detects a change in pressure, if the transmission integrity is compromised, and disables the energy source. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
