testing of an old 65 miles overhead power lines
testing of an old 65 miles overhead power lines
(OP)
Hi,
our problem is this: we need a test plan to test the insulation of a 65 miles long power line (2-phase 11.5/23 kV). The line has been down for a couple of years and now we have to energize it again. There is possibly 2 disconnect switches along the line so it can be isolated in 3x20 miles long parts. Can a Doble M4000 be useful to do this test?
How would you proceed with this test?
Thanks
JLuc

Anything else will not cover leaning trees, cracked poles, bird nests, broken insulators, leaning poles, or rusted transformers.
Otherwise I guess you could just wait for someone's attorney to call.

After inspection, then try energizing one segment at a time, preferably by operating an electrically operated circuit breaker, rather than a manual switch.
