I can understand Zs causing a trip, Ze I can't it's external to the system. The Ze (in my thinking) is line from the supply substation/transformer back to their earth spike (fault current) (TT). Any tripping can only be caused in Zs via R1 R2 that the RCD is connected. I can understand neutral...

This I promise is my last question - I want to do a 2 lead Ze using the 1651. Lets say on a TT system. I have removed/isolated earth conductor from the MET and am ready to crock an earth lead on and test to incomming phase. The manual still indicates a connection to neutral, and I can't get my...

:BlushingSorry above should read - connect both to neutral....

Thank you Andy, so just to clarify if I toggle (using F1) to either PFC or earth loop impedance, I still connect neutral and earth to earth in both instances for each respective test?

Hi, Forgive me if this post is answered elswhere .. :Blushing ...I cant find it, so here we go -Can I test Ze using just using line and earth leads on a bog standard Fluke 1651. If I want to find PFC can I manually switch (2 lead) testing between earth neutral myself. I don't want the bloody...
