I know that having a neon in the circuit screws up IR testing, but I just wondered if the same applies to Zs testing.
Many thanks

And resistance wise, I think the neons are 200k Ohms (ish), so even if they were in the circuit, they're not going to make an impact on a measurement that's 1 Ohm
Hi Joe - just imagining the earth fault loop impedance is expected to be about an Ohm (or so) and if somehow a neon was wired in error from L to E, then its 1 Ohm in parallel with 200,000 Ohms, which is 1 OhmI'm sorry Wilko, maybe I'm just being dense, which is more than likely but how would a resistance of 200k ohms not have an impact?
Cheers
your maths has had me flabbergasted and on 2nd thoughts my flabber has been gasted again. the answer is actually 0.999995 ohms. get it right.Hi Joe - just imagining the earth fault loop impedance is expected to be about an Ohm (or so) and if somehow a neon was wired in error from L to E, then its 1 Ohm in parallel with 200,000 Ohms, which is 1 Ohm
