Earth Electrode

[Hardy Sparky (Mvc)]

guys tell me if have three 3 phase boards one of which is suppling the other 2 

and its a TT system with a new electrode with a reading of 43.3 at the supply board 

wat sor os reading should i get at the other two boards and then at one of the sockets

Ra+R1R2 of submain, and R1R2 of final circuit, although parallel paths will probably bring the reading down a bit

hi i was looking for reading not how to test 

 

[Andy™]

posting the same thread 3 times isnt going to get you an answer any quicker

 

[NozSpark]

There is no point in starting 3 threads on the same topic, if you just do the 1 everyone will still see it and post a reply if they have anything they wish to add

hi i was looking for reading not how to test 

er... how exactly am i supposed to know?

maybe try figuring it out for yourself, since i have already told you roughtly what it should be

or maybe ask your lecturer

 

[Steve3948]

The results on your meter will be your answer to it all.  :Salute

 

[Hardy Sparky (Mvc)]

ASK YOU  LECTURER what sort of crap is that,  all i want to know is if you test are conclusive and make talk in a forum !!! But no i get some jumped up know it all !!! Hmmm

and how the hell am i meant to know that how this site works,  ive only used it 3 times 

 

[Andy™]

the only possibly answer is 29.99573 ohms

that a better response?

your not exactly helping yourself by giving just about no information and expecting an answer

Hardy,

It is not possible to answer your scenario with the information given.

 

[Hardy Sparky (Mvc)]

andy pandy your a funny man did you go to NICEIC school to learn how to answer back like that !!!!!!!

 

[Hardy Sparky (Mvc)]

ok sidewinder tell me what you need to know and ill tell you 

 

[Hardy Sparky (Mvc)]

could some one pls tell me what scoob and de-scoob

 

[Sidewinder]

Cable sizes, types & installed lengths would be a start...

 

[Doc Hudson]

ok sidewinder tell me what you need to know and ill tell you 

An illustration may help, If I have a piece of cable of unknown CSA approx 25m long, what do you suggest the R1+R2 values may be. Any person asking an incomplete question on a forum, then moaning that they cannot get any answer, may appear to be working well out of their abilities?

hmmm good point but not really fair i think I'm looking for a forum where people would have answered with a question to try and help, some people do not learn as well and are not as quick as others !!!!!  and yes cable sizes might have helped
