[QUOTE="UNG, post: 549593, member: 8931"] When you get threads like this where the supply voltage is an issue because it exceeds the upper 253v limit I do wonder has the DNO's attitude to voltage harmonisation played a part in creating the problem they now have, it's nearly 30 years since the EU voltage harmonisation was instigated and very little has been done to move the nominal voltage down across the supply network to the 230v level, even back in the 90's I attended a few DNO events on the subject and the concensus was the network will still work as it is so we won't do anything unless we need to repair or upgrade the existing equipment. Moving on I know of a number of areas where distribution equipment has been replaced or upgraded in the last 10 years and the voltage still remains 10 - 15v above the 230v nominal level or to be more precise at the levels it was at in the mid 90's, the additional problem the network has now is the uptake of solar PV which is generally pushing the network voltages up and there isn't much margin to play with before the 253v limit is overrun [/QUOTE]
