Socket Zs High

[Knobhead]

Moses, please before this develops in to bloodshed. Will you please go away and check your facts.
Your becoming what we refer to as a TROLL. Anything to start an argument.
This discussion could have reach a successful concussion ages ago had it not been for your misinformed, inane comments.

did you disconnect the neon before testing?

Nah. 1st rule of trolling is, start a contentious thread, then make no further posts.
He could be an amateur of course.

Not happy about your comments but I will give you benefit of doubt.

Please correct me, and point out which misinformed comments?

 

[Moses]

but my point was you dont just condemn the meter....its only as good as the test leads you are using....

Test leads are taken care of when you zero the meter, surely?

not if there faulty....it may appear that they have......

OP's end to end measurements indicate to me that there are no dodgy socket connections.
The difference (too large) between his R1+R2 and Zs measurements rule out non zeroed leads.
There's something else going on here. As someone already asked, where did he take his Ze.

As for the original Q about the one high reading, $%& knows.

Had it before Archy, where the end to ends were fine, and the socket connection itself was iffy, caused by dampness if I recall.

Is there an RCD (not reading through all this again!). Dubious 'no trip' readings?
Maybe he should retry Zsing with the RCB bypassed.

Personally, I'd pass it.

 

[Moses]

You could try a new CB, may be the Cb is faulty and giving a hi Z ?

May be link it out temporarly and the do a test to see if you get anywhere?

Yes I believe there is, this was my one of my first thoughts (dodgy no-trip reading) but the OP's other readings would have been similarly affected I would have thought.

The end to ends and crossover readings were reasonable, it can only really be at the interface between cables-socket, or socket-meter on that one S/O, the ring was extended to that S/O, ie. not a spur.

Edit: the high Zs reading S/O was also an outdoor type.

Edit II: the OP also said it was measured at the back of the S/O as well as with the plug adaptor

I was going to suggest something for a moment there, fortunately the alcohol has taken total effect yet...

The only thing I can think of is that the connection between the terminals in the socket and the incoming cable(s) is poor and that the test at the back of the socket was connecting to the terminals and not directly on to the cable. Re-terminating the cables in the back of the outside socket may resolve the reading, other than that, based on the information given, there is a physics anomaly on the ring!

^^^^^^^

That's what I said for the OP to check, many posts way back in this thread Rich, lol:rofl:

You did indeed; I am far too slow, I have just reread the whole thread(!!!) and saw your post, .
Still doesn't explain the highish Zs overall but would make it compliant for the MCB.

Hi Rich,

The OP never said if he did the (R1+R2) dead tests at each socket, I did ask.

The overall end to end and crossover readings r1 and r2 and R1+R2 were about correct and not too far out when added to the Ze.

My next move would have been to temporarily put the pairs of the Hi Z S/O conductors into three seperate Chock blocks or similar to see if I got more sensible/expected readings, and then replace the S/O if necessary.

I have had it before where the conductors have been twisted together giving reasonable end to end results, but poor at the S/O (slack terminal screw), or the odd time where the S/O terminal has suffered due to dampness/corrosion and gave poor or high readings, yet the end to end readings have been again reasonable.

Up date. Have found that when my meter says that it has zeroed the leads on screen that is not always the case, but when I turn off meter it should reset.Infact it still says that the leads are zeroed when I switch it back on but when I do a little check the leads are not nullified until I zero them again. Lesson learned and this may solve the problem will retest tomorrow.

Oh well, a decent outcome to one of the worst-answered threads I've ever seen here!
There's an old saying "Sometimes it's better to keep your mouth shut and look stupid than to open your mouth and prove it"

Nice one son!!!!

 

[telectrix]

never had these problems when all we had was avo 8's.

Not familiar with the AVO-8

But did you do ZS at that time or wireup and connect every thing and put in the fuses and if none blew then that's commissioning done?

"test leads taken care off when you zero the meter surely"... eh moses?...post #65...

They are taken care of if you zero the meter before every use!!

If you don,t know how to use your meter, then don't blame the posts!!

and how do you know if i know how to use my meter or not?....look,...i think your a slippery little character you....i noticed how your posts have altered a bit here n there throughout this thread.....early on...you refered to earth-fault-loop-impedence as PSCC....then you accused me of getting confused with Zs and Ze...i think not fella......then it was just plain Z.....

 

[GLENNSPARK]

you cannot absolutely guarantee that test leads will be nulled out succesfully first time every time moses....even just the crocs can give funny readings sometimes......and sometimes dodgy test leads will not manefest themselves until you start to manipulate them/move em around....such as you would to take readings...

 

[GLENNSPARK]

i dont just assume owt mate.....if i even get even slightly suspect readings...the test leads and the interface is the first thing i check....before owt else....
