Farms (particularly livestock) shouldn`t be provided with a PME earth
under the supply regs. Its down to the individual farmers to provide
their own earthing arrangements. There *may* be some latitude where
only
crops are grown.
Interesting. But we definitely have a utility installed PME system from
many years ago complete with pure green earth wire into the neutral
connection. I'll check with the other farms tomorrow.

I think I was drunk when I first posted the reply :-}

I don`t think they`re allowed to provide an earth by any means to a farm,
particularly with livestock - not just a PME :-}

ISTR any services from a stretch of overhead line that may serve a farm
with livestock along its length aren`t supposed to be provided with an
earth as it can change the line characteristics.

Some lines that have been refurbished may have an earth facility
available, but shouldn`t be used if livestock etc etc.


As this line hasn't been refurbished in the last thirty to forty years as
far as I can tell I'm now a bit concerned as to how well the other
farmhouses are earthed, if at all. As mentioned elsewhere I'll go test
them.

BTW, why does livestock make the difference ? Can't see how our sheep or
next farm's cows are going to reach any of the supply lines.
