In a street in Newcastle a frew years ago it seems there was some sort of power harmonic, as one poor resident had just about everything blow, even lights. The harmonic generated huge surges. Only his house was affected. He had to battle the authorities for years to get something done, in the end I think they had to re do the grid near his house.
At my place we get higher voltage than normal as we are right opposite a powerpole transformer. Voltage here ranges from 240 up to 250v. However we dont get unusually high appliance fail rates. My 5 year old PC is still going fine as a 2nd pc in the garage.
