	AOA Hi guys I am recently puzzled by seeing a CT on a rectangular bus bar (6.6KV) having a thin wire connected to the bus bar? any one has idea what is it used for? I s it a kind of feed back circuit like in closed loop Hall effect current sensors?

	Do you know if the buss was the neutral? Some differential protection systems may include such a connection for a neutral grounding scheme. __________________ I do not 'know it all', but i will admit that I would like to. CJM
