Maybe, in my dreams .
I’d start a new thread if I were you and explain why you are doing this in the first place. Only disconnect the main earth to get a Ze reading. Then do dead tests to investigate anything.did you finally find the root cause of your problem ? if yes i would appreciate you share it. i have the same. w / wo main Earth wire connected i read same Zs 1.5 ohms. ( TT system) . thank you
I have a TT system ( earth not connected anywhere in any panel with neutral ) and the result i git for Zs was too good to be true . I understood that for a TT system you can not get less than 10 ohms but in my case was 1.5 ohms. I just tested w/o main earth connected to see result..like trying to understand the phenomenonI’d start a new thread if I were you and explain why you are doing this in the first place.

A Zs test with the main earth disconnected should never happen.
I understand what you are asking - you are saying how can the earth path be this good.I have a TT system ( earth not connected anywhere in any panel with neutral ) and the result i git for Zs was too good to be true .
