Hi, I was doing some work for my grandparents which involved fitting a blank plate to an old spur unit which supplied an outside floodlight which was still live and they wanted it disconnected, easy enough I got the job done but I was a little concerned about the voltage level, when testing my meter read 256v! which I thought was a little high. I measured some other circuits in the house and got pretty much the same reading 256v or 257v!.
As far as I am aware they have never reported any problems with their appliances but I think this voltage is little high. There is substation at the top of the road which supplies the whole street and it is about 200m away from the house so I wouldn't say it is exactly close. However there recently two tower block council flats demolished at top of road which this substation also fed. Perhaps this could of effected the supply voltage due to major decrease in load at the substation. Does this sound likely? or could a loose connection somewhere in the house be causing this high voltage.
cheers sorry if it doesn't make much sense its late and I am tired.
