Hi Guys,
I have been testing for about a year and have come across my first tt system yesterday.
I disconnected the earth and tested for Ze and got 8.67 ohms which I believe to be a great reading as osg allows up to 200 ohms. I couldn't do a Ra reading as the rod is under the house and impossible to get to.
But when I'm doing all the earth loop tests on all the circuits I'm getting similar readings between 7ohms to 9ohms. As I havent tested this before and not really sure on it I dont know what im doing wrong, what the problem is and how to fix it? So any help would be great if possible.
Many thanks.
