Gents,Had posted this in but was told that this is a much better place to ask. The main reason is that I've heard some horror stories from Australians about line voltages shooting up to 270V, UPSes blowing up and so on, but this was more inland.A product is going to be test marketed in Australia, northern half of the east coast. We know the line voltage there is 240V/50Hz but not which tolerances apply. The upper limit is important to us, and also whether it tends to exceed whatever the standard might say. Can someone elucidate?-- Regards, Joerg"gmail" domain blocked because of excessive spam.Use another domain or send PM.

Yes, the line voltage often does exceed 240V.The line voltages at my place (Sydney, north west, Hills area) are 257.3V, 259.4V, and 257.8V, at 2:10pm today. They do go higher at night. The are about to bring a new substation on line. That may improve the voltages.Energy Australia (our local network provider), have a nominal tolerance of 240+/- 6%, but allow it to vary from 216V to 264V active to neutral.David

Line voltage north-eastern Australia?
