Earth Leakage test with a Megger MFT1730

[moorekw23]

Can anyone recommend a clamp that can be used with a Megger 1730 to measure earth leakage?

If you look at the pdf here you'll se at the bottom it shows the optional current clamp.

I'm not convinced this instrument is capable of accurately measuring in the 0-30mA range. Maybe someone with first hand knowledge of the tester will clarify but I'd be tempted to buy one of these for leakage current measurement.

well one of my MFTs will measure leakage...but i was never able to get a leakage clamp for it....
if you want a leakage clamp thats reasonably priced...and works OK then theres these:

AMECaL ST-9810 Mini AC Leakage Current Tester: Amazon.co.uk ...

now, i have one of these...and i`m happy enough with it.....
its 0.1mA resolution
and it goes upto 200A.....

i use a beckmann industrial clamp with the MFT i have that will run it...:

these are not now in production...they have an adjusting wheel and a switch for high and lower current ranges
they wont measure leakage
these can be found on ebay for the £15-£20 mark plus any postage....
and they are very high quality stuff...
the dedicated leakage clamp together with this for the megger 1630 may be a better option....

you run these using the neutral and earth plugs on the MFT
