Ir testing

[glasgospark]

ir testing today on 6 circuits all >999 apart from sockets which was around >500 odd,

every socket unscrewed and walls being plastered no bags over sockets , im thinking this may be effecting the results , loose connection/condinsation etc

>500MΩ...you're 'avin a larf ain't chya?

???????

 

[telectrix]

> 2Meg. is OK. >500Meg. be happy or you need to get alife.

 

[Silly Sausage]

>500MΩ...Instant Pass, move on!!!

 

[glasgospark]

lol

i know its a pass, 0.5M is the minimum

i wasnt saying it is a fail was wondering why the meter would >999 the rest and not the ring so obv something causing it .

Hard to please some folk

 

[telectrix]

breathe on the crocs will lower the reading at that level.

???????????????????????????????????????????????????????????????????????????????????????????????

mearly questioning why guys i havent failed it by lack of knowledge or even planning on any remedials

Put it into perspective,
@ 500Meg, you're leaking <1 µA, through resistance.
The circuit will be leaking considerably more than that through the capacitance of the cables when energised.

At those levels it could be anything but again nothing to worry about. Other option is to use a megger that only reads up to 299 Meg then you wouldn't even be asking this question. :lol:

lol good shout ill kewtech it >200 lol

 

[Sintra]

That's it mate problem solved :lol:

 

[Silly Sausage]

Now go and empty these...

 

[glasgospark]

oooh , that looks tghe business

Elaborate on this please. Are you thinking about ELV?

0.25 my apologies your highness

 

[glasgospark]

250v 0.25
Upto 500v 0.5
Upto 1000v 1.0

 

[telectrix]

Now go and empty these...

and after such a daft question, fill these.

 

[bartkusal]

250v 0.25
Upto 500v 0.5
Upto 1000v 1.0

Wrong, the correct values are:

• SELV and Pelv, test voltage 250V, min IR 0.5 Mohm
• Up to and including 500V, test voltage 500V. min IR 1 Mohm
• Above 500V, test voltage 1000V, min IR 1 Mohm
