tpn Ze readings

[brs73]

hello there
i've tested the ze on a three phase tns supply
my results were
brown 0.22ohms
grey 0.22ohms
black 0.24ohms
what result do i record
all three?
an average?
the highest?
the answer is probably already posted but i cant find it
thanks in advance

I normally state the highest, as the highest reading should be recorded.

Other people will post a reply stating reg No's, with out my BRB i can not quote them......my memory is going as i get older !!!
