Field Insulation Test

Just a quick video showing the Megger in action in the field.
I started by making sure the conductors to be tested were clear at the other end of the circuit.
I also terminated the equipment ground conductors at the other end of the circuit and verified I had a path to ground via an ohm test from those grounds to a nearby footer steel connection which turned out to be .4 ohms. There is a lot of grounded steel on this project so this was a good reading to have.
I ran the test on all conductors and they all tested out at 2.4 megohms and higher. I needed to see a minimum of 1 megohm so this gave all conductors a passing grade.
Sorry about the background noise, these jobs are noisy!

I have never heard of anything like that. That was cool!

Thanks Brian! I get a bit worried about long underground conductors and like to have the comfort of mind to have them tested prior to flipping on the switch.

BEEBBEEEBBEEEB.....!!!!

Congratulations! Thank you for joining the channel!

[@ketas]

at first i thought that conductors are normal sized and ladder and room is extra small, but then i slowly started realizing that those are arm sized...

[@TheElectriciansGuild]

Haha, they are about 3/4” in diameter.

What is the difference between these cheaper insulation meters and a megger? Just the sensitivity?

[@davidiliyn]

This is a megger.

[@kpmurray8406]

All phase conductors that are not being tested should be grounded during the testing.

[@TheElectriciansGuild]

Would this be a safety precaution?

That cable doesn't look good..

[@TheElectriciansGuild]

The last 4’ did get scraped coming out of the connector during the pull. They did test out though so it’s all good :)

@@sircampbell1249 Haha yeah, these pulls were 1080' long, we had a lube pump on the feed end. Not sure how many gallons made it into the pipe, but it was a lot.www.polywater.com/en/product/polywater-nn-lubricant/

@@TheElectriciansGuild All that damage to those conductor sleeving, meanwhile we see standards elsewhere lugging massive 3 or 4 conductor armoured cables without issue. In north america that steel conduit always rots out with rust in outdoor salt settings... the standards in North America don't appear to cause less electrical fires either, only cost significantly more money?
