Megger

[brian john]

That is not my tester I have no idea why the boot is removed. EXCEPT I always throw them away as the fatten up my already too over burden tool case.

I resized the slide show so hopefully it loads faster and plays on slow connections.

I just stumbled across this, and am adding it to the table of contents on the FAQs.

can you test loop impedance with any megger? and do you test with the power on or off the circuit? I found this on the fluke site and think it would be a great trouble shooting tool. In the diagram/ picture on the fluke siteI get the impression the power is on.....however this sounds wrong after reading this thread.
I am a megger newbie and have never used our megger. It is very very old, I can't think of the model at the moment.

Testing Z's is best done with equipment other than an insulation resistance tester. Matter of fact, I might say that it's rather impossible to do with an insulation resistance tester.

Fluke has a model 1653 which is a loop impedance tester and a megger which isn't marketed in the US, only in the UK, etc.

It's a megger but it's seperate like having two different units.

The Fluke 1653 can't be purchased here "normally" although there are a few that have them. It unlike the Suretest 61-165 that does loop tests, won't trip a GFCI. I was lucky enough to have use of one for a bit!
