Property had poor Ze reading on a TNS system.
This (eventually) was changed by the DNO to a TNCS system.
It got me thinking about the checks that the DNO do to the property when changing the earthing type.
No comment or advice was given to the home owner about the possible consequences, and no checks were made.
I am thinking about exporting the PME.
This is a big house with a large garage and a office 'shed' which could easily have earthy metal.
I would have thought that the DNO would be checking that the change to the earthing would not affect the installation, but it appears not.
I've been quite surprised by my recent dealings with the DNO.
