Earth Leakage Clamp Meter Question

[oldtimer]

Not entirely related but might cheer the poster up a bit. I'm working in a hotel where circuit earths (where present) occasionally present anywhere between 90 and 120 VAC. Sometime sthey splash a bit on re-connection.

Zs is impossible meter just screams

I am almost at the point of screaming too. Wierdly, there is 0V to water earth bond or pipework

The 90-120v on the earth sounds like a broken earth on a lighting circuit ie holgen lamps hence why Zs cannot be read.
