Megger standard for 600V cable

[Designer69]

hey guys, I thought IEEE 400 was the standard when it comes to megging power cables, come to find out it's only for 5KV rated cables and up.

anyone know what the standard is for the lower voltage ones??


TY

That would be covered in one of the color (IEEE) books, depending on the type of facility. You have a specific question? You can always reference ANSI/NETA Testing specs if you just need a reference.

As per NETA Acceptance Testing 2007:

Typically 1 Meg-Ohm per kV is an acceptable value.

No, that is not anywhere in the NETA specs. And nowhere near acceptable. NETA specs have 600V cable as a minimum spec of 100 Megohms.

so is the NETA the governing standard nowdays?

Not really, it is a recognized ANSI standard, however, only required to be followed if the specs require it. There is no "law" that says what your minimum IR needs to be, just recomendations from ANSI, IEEE, NETA, ICEA, ,etc....
