thats the one , also our house has a transformer on the pole outside, it only feeds our house,so if the transformer takes 3300V and turns it into 220V then to get a spike of 1000V you would need to put 49500V through the transformer! seems a bit when we moved in the house (29th july this year) within a couple of weeks they came and changed the transformer and i did ask if we keep old one, but they wouldnt let me have it something to do with the coolant and the value of the transformerUsually 3.3kV.
