Megger Testing of Instrument Cables
Megger Testing of Instrument Cables
(OP)
Hi all,
It has been my experience and I have heard from others that it is not standard procedure to Megger instrument cables. In our specific case we are using a 300V cable for 24VDC service. What is the forums opinion of Meggering instrument cable and what megger setting would be used for our DC cable?
Thanks

besure to discharge the cables after charging them up, if not done properly the charge will rebuild on its own, as the dielectric relaxes to its uncharged state.

However I wouldn't let a megger anywhere near instrument cables. Check your cables with a multi-meter.
Yes, disconnect both ends before testing.

moisture in the cable. The Ohmmeter is looking only at the resistance; the TDR is
looking at the total cable impedance. The total cable impedance includes the
resistance, the capacitance, and the inductance." By looking at the whole picture you can get a better look at what is really happening. check out the whole information here. h
Good luck
