Voltage on gas pipe to boiler - newly qualified question!!

[a1guvner]

Time to jump in with your IR tester before you rip the place to bits, get your overall IR upfront on the ltg ct if low then start seperating suspect parts of the circuit and retest and narrow it down

Your tester will give you clues quicker than exposing questionable areas and doing visuals

Yes mate: Thats definately a possible hotspot, something has me a bit confused. What sort of non contact tester picks up on 5 volts ?. then as a1 says i'm afraid it's time for the Megger & a nice little tracing session.

The flukes and kew techs both seem to light up around 6v.....

That's brilliant for a Tester that's not supposed to light up below 100v, think i'll stick to my MK tester. What was the result of your insulation test on the upstairs lighting circuit ?

What tester do you have?
Do you have a link?
Cheers.

It's the MK LN6090 the 1 with the sensitivity control, sorry mate: have'nt got a link but try the TLC website or Test-Meter.co.uk might do them. It's the only 1 i've found so far that does'nt pick up on ghost voltages.

It's my first job when I return there on Friday. It's been great to get some ideas from everyone, thanks for he heads up. Will post what happens in this thread on Friday.

Fluke Ldv2 is a good little tool

I have one too and can confirm that it's quite insensitive to phantom voltage, but it's not infallible.

Where is this voltage being measured and with respect to where? A voltage cannot just be "there" its got to be measured between two points , It is after all A POTENTIAL DIFFRENCE.

The gas fitters simply stick the pen tester on the pipe, therefore it is the potential difference between the gas pipe and where they are stood. Or is that a little simplistic?
