Hi peeps....
Just been reading about these tests and was wondering.....
When measuring Ze we would carry this test out with the earth conductor temporarily disconnected from the MET, which will also count out any parallel earth paths and a false Ze reading.
Add the Ze to our R1+R2`s of each circuit and we get our Zs`s.
But..........
When carrying out a straight Zs test on an energized installation,all main equipotential bonding will be in place and the reading we get will include these parallel paths.
Is there any way to eliminate these parallel paths?
