UK voltage

[RF Lighting]

Rubbish. Measure it.

Following on from this statement, I’ve just had a look at my power meter and here you go:

Just thought I’d make sure it’s reading correctly with my calibrated MFT.

mine is currently 232v

never seen it so low

usually 240-244

244.4v here at the moment.

 

[oldbutnotdead]

235.2 in damp North-East, usually nearer 240

I was out on a call yesterday evening, customer complaining things failing.
voltage measured variously between 235v and 245v L-N. Sadly 410v N-E, 630v L-E and unstable 200v to 350v E- earthspike.
DNO came quickly and pulled tails and bonds. Generator provided today for about 10 properties.

At home now 235.7v, a few years back it would have been 250v to 255v as I'm very near the sub.

 

[JohnD]

frequency is currently 50.07 Hz and generators are lightly loaded, so it shouldn't be that.

Is it because of high winds, that is resulting in wind turbines being taken offline?

What shouldn't be that?
Frequency here 49.9997Hz averaged over 5 minutes, 49.9989 min 50.0004 max using rubidium standard

 

[JohnD]

What shouldn't be that?

the voltage shouldn't be down because of heavy load.

now 50.00
perfect
(mine only measures to 4 sig fig)

wind is now generating 11.6GW, which is fairly typical

Windspeeds over the country are not particularly high at the moment

You should see our trees!!!

 

[Risteard]

Voltage always very close to 230V here.

Forget ~@winston/GeorgeCooke and his fictitious makey/uppey 240V.

if they're still right-way up, no prob.

I don't think I've ever had it as low as 230v at home. As mentioned earlier It was always well over 250v here and often 260+v.

At my first house I was the first house on a run of 120 houses, while doing it up I got through so many bulbs I checked the voltage regularly and 260v was not uncommon. I complained and board came out to fit a pen recorder. Scale was 200-300v and there were regular spikes over 300v. They gave me a missed box of rough service bulbs as an interim fix. Eventually they fixed the problem by adding another cable to feed in to the far end of the circuit.
