IR testing

[Pete999]

Now that I'm a retired Electrician with nothing to do other than annoy Forum members with inane posts, and browse the net.
I came across some American videos about MICC installations, and having worked in the states on many occasions I found 1 vid rather interesting, a guy "Russ La Blance code violations" Russ was testin IR on a 2 core MICC cable and referred to the minimum Meg Ohm reading between the cores and the cores to Earth as 100 Meg Ohm, anyone got any thoughts, just interested that's all, as most of the American Sparks I worked with just did the bang test," would love to hear any thoughts from any of our American members as well, another inane post, sorry

I disagree. I still find myself doing plenty of tricks,which hark to an earlier period...

You just dare not pass it on,explain it,back it with a reg...or...say it on a forum! :aureola:

I happily pass on and explain many of the less than modern methods I know. But sure as hell won't ever admit to them on an open forum.

I wonder how many people on here have synchronised multiple big generators with just a couple of GLS lamps, a switch and cast iron underpants?

Know the theory not seen it done as you have to throw the switch in the dark

These days I dont play with MICC cable as much, then if I do its probably an imperial sized pot to replace. My comment on doing them these days would be more inline with the health and safety, and any RAMS that would need to compliment the job.

I dare say there is nothing wrong with putting 110V down a cable all weekend,as long as it was correctly done, warning labels secure termination and jbs etc. But the amount of houses with MICC cable these days you will not count on one hand unless specified, maybe a thatched roof cottage etc.

Im sure there is no regulation for heating a MICC cable up and drawing the moisture out,but it is one method that works and is still often used under the correct guidance and risk assessment. but there is definitely chapter 42 !! if you really want a regulation. But that is not for putting a naked flame to a MICC cable to draw moisture out

There you have it I cared to explain, I backed it up, and mentioned a reg.. Sunday morning graft done.

In the good old days before CT testers, to find a fault on a buried cable was the old wheatstone bridge..............but that took a little bit of time and quite a bit of savvy.......................

The other way as told by the "older hands" remove fuse from carrier............replace with a hmmm suitable medium and isolate before refitting carrier.................turn on and the fault becomes evident with displaced earth..............seen it done once but never had a pair larger enough to try it myslef

Only the once, and that was in Cyprus well away from prying eyes

Tony has a wonderful anecdote of the time he felled a tree using that fault finding method.
