In Mike Holt's video (part 3) about pools and equipotential bonding he shows how he gets "neutral to earth voltage" (NEV). He goes 50' from the transformer and sticks a screwdriver in the ground and connects one of the leads from his DMM with a long cable to the screwdriver. Then goes to a pad mount transformer and touches the other lead to the metal cabinet of the tranny.
That I understand but I have a question... What if the tranny is a pole mount, what do you connect the other lead to? Maybe the ground wire from the tranny to GE?
I got a call wanting me to check a pool where they claim to be getting shocked. I was going to use Mike's method but most of the trannys here are pole mount. Even if they have underground to the house the tranny is still a pole mount. Just need to know what to measure to in that case.
