Now surely in the real world

Ze +R1&R2 should be more than Ze mmmmmmmmmm no Ze of .47 yes I know but its not TT its PME,d at the cut out but, Zs at socket .41 SSE have been so hopefully its resolved, anyone else had this

Yes, Ze + (R1+R2) does not factor in parallel paths.

Zs is also total impedance rather than Ze + some resistance value. As impedance is an active value, it can vary.

Or at least, that's my take on it

Ze + (R1 + R2) does not also allow for poor joints ............

 

[Richard Burns]

Ze is < Ze +(R1+R2), however Zs as measured can be < Ze+(R1+R2)
Maximum Zs is Ze +(R1+R2) but measured Zs can be lower.

sse had been, and a poor link between neutral and earth at the cut out was the culprit

Meter fitters doing loose connections again!
So a variable Earth resistance was the cause of the misaligned readings, Hmm, have to remember that next time I get a high Ze.

Mhmm so to unravel that a bit, you @the pict find your Zs lower than Ze. It has been mooted (correctly in my understanding) that paralell paths on actual Zs may account for Zs being lower than Ze. The DNO came and tightened a PME connection at the cut-out. You say this was the reason you had lower Zs than Ze. I am a bit confused as I would have thought you would have a variable reading if the connection of earth to the PME terminal was poor? But is it really the answer, what did your subsequent test reveal, you left the issue open to conjecture with your statement.

Sounds like you're waiting for the Orgasm Vorti

How about that edit then! Too early for such things.

 

[the pict]

not been back yet, info from the customer so sorry i cant enlighten you further

 

[The Ghost]

Lucky the customer knows about these things then.

...or just give yer lead plugs a sandpapering...
