Hi guys just a post wondering how people conduct their r2 tests. In the OSG it says to do it with a long lead attached to the met and test cpc at various points, what happens if you don't have a longlead? Is there an alternative?
R2 is generally only used for bonding.
Does r2 not have to be recorded on a periodic?
R2 is generally only used for bonding.
R2 testing can be used quite a lot when carrying out PIR's, especially on commercial or industrial premesis where parallel earth paths are in existance meaning an R1+R2 test is useless unless you can remove all parallel paths.
Does r2 not have to be recorded on a periodic?
I assume you mean R2 and not r2?
r2 is the cpc end-to-enresistance of a ring final circuit.
yes I do mean R2 so do you use test method 1. Or 2?
Does r2 not have to be recorded on a periodic?
Either R1+R2 (test method 1) or R2 (test method 2), one or the other.
When using test method 1, polarity is confirmed as a matter of course whereas if you opt for R2 testing then you need to carry out a separate polarity test.
I assume you mean R2 and not r2?
r2 is the cpc end-to-end resistance of a ring final circuit.
Maybe not but an R1+R2 test would be just as meaningless.
R2 testing is faster and involves less disruption to the installation.
As part of a PIR the R2 test is usually easier as it involves less dismantling.
