Friend of mine got a new computer today and when he plugged it in it blew up, quite literally! He then plugged in his lap top and that too blew up though it has been working ok during the week. (He moved into this property last weekend).
On checking his supply voltage it was reading steady at 306v. I double checked a number of outlets and received the same readings throughout the property. Coming back home and my supply is steady at 251v (inside the permitted parameters). Both systems are TT though the high voltage one is in Norfolk and ours is in Suffolk. I'm suspecting the pole mounted transformer at my friends is at fault and have advised he contacts the DNO now as a matter of urgency.
Has anyone got any views on this please?
