Insulation resistance testing

[Majid Khan]

Hi guys,

Could anyone help me Please with the following questions? I have an assignment to do which has a question that states, Insulation resistance testing has been carried out on the installation and the following result obtained:
Live to Live = 195 M ohms
Live to earth = 0.75 M ohms

Question 1, Determine whether these test results are acceptable.
Question 2, state the actions to be taken should the test result be unacceptable.

Thanks

What do you think the answers are?

Best to post up your thoughts then we can see what parts you don't understand.

I just need the answer of these questions and these questions are related to the 195Mohms and 0.75 Mohms. if you can help please.

So 2 polite people have asked you to offer up YOUR ideas so they can comment .... and you don't....

I'll tell you it's not acceptable and you tell me why it's not?? And possible reasons for the reading?

 

[kingeri]

Just tell me the answer and shut up.

 

[ChrisElectrical88]

In fact if it's ELV it could be acceptable.

LOL ! everyone is offering help and he still wont give a answer

1 of them is not right
1 of them is wrong.

Actions required; get the readings to an acceptable level.

I really do not know the answers. thats why I put the question here.

You need to research the subject better and post your answer here first before you will be helped.

Okay, lets get the ball rolling. What is the minimum circuit insulation resistance required between L and E according to the regs.....or even according to your college notes?

Don't you even have a clue Majid?

The minimum IR according to reg is 1M ohms

ok if i got he answer of 1st question, what about question 2?

 

[Gavin A]

Live to Live = 195 M ohms

do they actually refer to it as testing between Live and Live these days then?

not happening around me, far too confusing.

The minimum IR according to reg is 1M ohms

Okay, according to your question you have an IR of Live to earth = 0.75 M ohms. Obviously 0.75 is less than the required 1Mohm so we know it's not acceptable, the remaining question is 'state the actions to be taken?'
