TT system stand by generator

[gurungtp]

Can anyone tell me if a test is to carried out to establish the resistance of earth electrode for a generator providing alternative supply
1)what must be agreed before test can begin?
2)Action to be taken with earthing conductor for generator before testing can began.
Action to be taken with generator before the action of above question 2
3)Instrument to be used and earthing conductor after the test.
Thanks

Get in touch with the DNO.

Best of luck getting any sense out of them.

Is this a homework type question or a real life problem?

I know what I think it is.

If he looks the information is out there.

I’ve just downloaded a mass of UKPN documents on supply requirements.

Standard home work question
seek permission to isolate, disconnect earthing conductor having switched off, isolated and locked off generator, testing using an earth electrode resistance tester and reconnect earthing conductor before re-energising system.

You will really not learn anything from just getting the answers, try and think about why you would do these things and why in that particular order.
This is all very similar to a standard Ze test on an installation.
Do try and think about the questions and give your ideas on what the answers are, then you will learn something.

Why?

Will people never learn!

The idea of homework is for the student to do the work. NOT to come on here where some numpty does their homework for them.

He’ll not have the internet in an exam.

Sorry Tony, I should not really have answered but this is just so basic, I did feel that there was no chance of getting anywhere if this question is not easily understood and answered. Sorry for being a numpty!

You’re forgiven, you would have been slaughtered on CR4.
