gas earth bond

[m1ck_b87]

Hi all
Any 1 come across voltage on main bonding conductors before

 

[Deleted member 72666]

What sort of voltage is appearing, what is connected and where are you taking your measurements from?

 

[m1ck_b87]

Edf came out and used a voltage pen on earth connection and said there was voltage, I've come and tested across gas bond and exposed conductive part no voltage

 

[oldtimer]

Have you :-
1. Checked the Ze of the property
2. Checked the continuity of the earth cable from the MET to to earth clamp on the gas pipe.

you might not have an earth at all based on that.

Yea but what pillick in EDF used a voltage pen instead of a earth loop impedance tester and thats why I asked the questions above . I take it you are a electrician ? and if so have you tested the Ze yet

 

[chrish_1977]

A voltage pen, time for me to sell me test kit then I that's all you need. Seriously I have a builder friend who said the same to me, when I actually tested it with me megger, low and behold all ok, were edf touting for work or something, sounds like they have been to the bg school of testing

 

[oldtimer]

Either that or the EDF guy was a saleman who knew nothing about electrics except for the half day monkey see monkey do

:38: .

 

[telectrix]

should exchange it for a broad tip felt pen and write "muppet" on his forehead.

 

[Silly Sausage]

The more I read of threads like this, the more and more convinced I am that it's not what you know, experience you have or how competent you may be, it's the ability to spout Bull at interviews!


edit: I'm referring to the EDF geezer!!!

 

[Tidy Max]

my volt pen also reckons theres voltage running through my index finger, my forehead and this lump of 3x2 next to me!

When ive got mine in my pocket it says my leg has voltage when i walk, should i be worried?

is it your voltstick, or is there a hole in your pocket?

 

[tony mc]

So what has the EDF left you in writing or has his /her pen been replaced with a volt pen. Seriously I would like to know what they have said is the problem and I would like to think they have documented it!

 

[oldtimer]

Once again we are talking amongst ourselves and the OP has went quite

Just to add yet again it appears that someone wants an answer before they visit site it would have been better if the EDF stick came along with a and I did a Ze test and found.........

 

[m1ck_b87]

No I never did ze test, quick voltage test and touch test jobs a good un

 

[oldtimer]

No I never did ze test, quick voltage test and touch test jobs a good un

Well no doubt you are right because if you did do a Ze and checked the gas earthing for continuity you would not be on here asking the question time to unsubscribe from this tosh

 

[GLENNSPARK]

No I never did ze test, quick voltage test and touch test jobs a good un

was this before or after you licked your finger....

- - - Updated - - -

or were you busy lickin the window?

 

[m1ck_b87]

Licking the window

 

[tony mc]

So hypothetically a problem arises at that house and someone is injured (I hope not) & it is discovered that the premises has no earth ! I wonder who the finger is pointed at !

 

[m1ck_b87]

Why Wudnt there be an earth

 

[tony mc]

I take it that is not a serious question !

 

[SirusDvirus]

lol..volt pen??..just thought I'd chuckle

 

[m1ck_b87]

Could be induced voltage doesn't mean there's no earth

 

[markythesparky]

Why Wudnt there be an earth

because earth has 0v, and anything connected to it would also be a 0v. Therefore to answer your other later point, even an induced voltage, once connected to earth would be 0v! if you disconnected it and tested to a known earth you would then see a potential difference. if you connect it back up again it would be 0v.

 

[m1ck_b87]

I tested between gas bond and an exposed conductive part and it was 0v

 

[markythesparky]

That's probably because the exposed conductive part isn't connected to earth either. Therefore neither are at 0v

Edf came out and used a voltage pen on earth connection and said there was voltage, I've come and tested across gas bond and exposed conductive part no voltage

what a cowboy. these guys are meant to know what they are doing!!!

 

[m1ck_b87]

Ok but why would there be voltage down the main earth bond if There's no earth, don't forget u can get earth leakage aswell

 

[markythesparky]

I presume you mean from the EDF's glow pen? If so this is probably being induced from other circuits and because its not connected to earth (0v) it cant discharge.

 

[Tridentsystems]

No such thing as main earth bond

yeah uve got a fair point

 

[Marvo]

Are you being serious?? If so I can only weep for the electrical industry and what it's become...

Do the EDF technicians have a 'yes/no' tick box for the volt-pen lighting on their inspection sheet?

 

[terminator]

Why was EDF there in the first place?
Why was he testing the earth bonding (albeit with the wrong instrument)?
Is the installation earthed?
What type of eathing system is it?
What tests have you carried out?
What are you trying to do?
Is this connected to your question in another thread?

Most of these answers are in this thread.

 

[terminator]

Well it would be nice if the OP would answer them, because I haven't seen satisfactory answers to any questions so far? Especially my last two.! It has all the makings of another heated discussion between peeps trying to help, and the OP disappearing without trace!

Agree.............but depends how old you are :8:
