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!
