How the hell has this thread re-surfaced? My post to which is refers was

the plate says 240V AC; hope it copes with 210- 230 volts that

I used to get 242 volts and hardly any variation up to about
a decode ago, now it varies from 211 to 226 volts

Some local issue to you then, ours has always been 240v +-2v

My understanding is that the supply voltage has not changed, only the
nominal voltage. Someone will have the figures but I was told the
narrow band round our 240V fits inside the wider band round 230V.

Locally something could have changed of course.

Yes back in the 80s there was a home computer called the Lynx. It was a
fairly good machine for the money but a lot of the power supplies went down
due to being made for 210 5o 230 mains. . I know they did get very hot, but
I find myself still sceptical that running them at around ten more volts rms
would cause the problems observed. they said made in France but who knows
what rubbish they were actually made from.
Another friend of mine bought a small TV in Hong Kong around the same era
which was supposed to be plug and play anywhere in the world, and the t v
did, but the power supply welded itself to his coffee table it got so hot.

The UK supply voltage used to be 240V ±6%, which is 226V -
254V

European voltage was 220V. Assuming the same ±6% tolerance was
used, it could vary from 207V to 233V.

Europewide it is now 230V ±15% (I think) which is 200V - 264V.

A 10% tolerance would be better: 210V - 253V, so perhaps my
memory is playing tricks on me.

Antway, as you say, no change the supply volage change is/was
necessary either side of the Channel.

The last time I looked we were still running 240V and most of mainland
Europe 220V, we just rewrote the tolerances to harmonise the different
supplies.

So French nominal 230V is -10% +6% (207V - 244V) and English is 230V -6%
+10% (216V €“ 253V)
