High zs reading on a radial circuit

[simbin]

I have a high zs reading of 312 ohms on a radial circuit, r1+r2 is 1.82. Earths seems fine in the sockets....any suggestions?

Quick i have a fault on a circuit and don't know what to do, I know I will ask on the internet .

What is the Zdb

 

[Richard Burns]

Is this a TT earthed installation?

 

[simbin]

It's a pme, Pfc is 5, ze o.06

So where do you think the fault may be then?

 

[Richard Burns]

Do you have a high resistance reading across any of the protective or isolation devices that this circuit uses in the board?

Test each of the sockets in turn and see what the readings are?

A reading like that suggests the cpc isn't connected in the cu

OP why not ask your boss or someone else you work for some guidance?

GN3 is the way to go here, have a read cos I dont think you are applying correct I&T procedures

Take a chill pill.

Take a chill pill.

To be honest,i would not advocate the ingestion of any non-prescribed medication,in order to assist the facilitation of correct test procedure...just say no :conehead:

OP - Your profile does not define your level.... if you don't fill in your profile and post in the main forum you will be assumed qualified unless stated.

If you are qualified I suggest you re-educate yourself with your college notes as this is not a question I would have thought of a professional.
If your still in training then ask for access to the trainee's section where allowance for your lack of knowledge are made and help is always at hand, also you should be under instruction and the best person to ask is those monitoring you...

Like anything break it down and try to help yourself before asking, just taking a reading then jumping on here because your stuck isn't the way you were taught I hope, have you investigated the issue and if so what have you done?

So having established that the problem is internal to the installation, or so it would appear. How do you propose to bottom this one out?

As you say the R1+R2 and Ze are good, I would go with Richard's suggestion.
