Hi
could someone please help me with a C&G question
when testing a TT earthing system for external earth fault loop impedence using a earth fault loop impedence tester
Why the earth fault loop reading can be recorded as the electrode value
Is it something to do with the resistance of the secondary winding , line conductor as well as the earthing conductor miniscule in comparison to the resistance of the general mass of earth
any help appreciated have my 302 exam and this is one of the questions that is niggling me of sample paper i have
cheers for any help with this
