Shorted pilot wire in a 15KV trailing cable. - 06/29/05 03:30 AM
Anyone familiar with trailing cable? I have a 15KV shielded cable with 3-1/0 phase conductors, 2- bare ground wires, and a #8 pilot wire. I meggered the pilot to ground 0ohms@500V Shorted. I then checked it with a circuit seeker but it showed an open circuit. So it's a insulation problem with the pilot wire. My question is: Can I use a thumper on such a small wire?(I think I know the answer to that) If not what can I do to pin point the fault? Aside from cutting the cable in halves and using the process of elimination. Any suggestions would be great. Thanks.
