Zs to high

[Risteard]

do you mean periodic inspection
and not periodic inspection and test as it says in gn3

Periodic inspection and testing would be a satisfactory answer. You have a Periodic Inspection Report rather than a Periodic Inspection and Testing Report so I can't see anything wrong with periodic inspection either.

thanks risteard mate
only realized other day i was writing periodic inspection report doh

could you tell me two formulae for ZS is it
ZS = ZE+(R1+R2)
ans ZS = ZE + mohm/m x mf x length divided by 1000

and the Min value you reckon is 1Mohm
what page of regs as ive looked and only where it says 1Mohm is as i stated in earlier post for surge protective devices left connected at 250v d.c. 1Mohm min
and selv to band II

Had a flick through and can't find it. Will have a look later for you.
