At my job we have been working on underground 15kv high voltage feeders. The only way we have to verify the line is dead is an amp meter, but that only shows there is no load on the line, is doesn't verify the absence of voltage....The only high voltage meter on the job will not read through the wires insulation.... can anyone tell me where to get a meter that will read through high voltage unishield insulation, or tell me a different method to check the wire..........thanks
