High voltage plug sockets

[Alison]

Recently changed plug sockets and light switches. Have noticed before this was done we were burning through light bulbs.

A few of our plug sockets are high voltage 250 -270.

Any ideas

That’s not high voltage, it’s low voltage

They’re lamps not bulbs

The light bulbs are fine newm the plug sockets are showing 250270 v

If you have 270 V between live and neutral then yes, that is a little high. How did you measure this?

We used the red and black thing that gives you a reading

 

[DPG]

Do your neighbours have similar problems?

 

[Alison]

As far as I know no but I do know one of them might as they r changing alot within there house

250V is normal for the UK, this is what most substations are set up to supply.
270V is above the normal limits and if this has been measured with an accurate calibrated meter you should contact your distribution network operator ASAP to report the fault.

It was supposed to be a joke. Sorry you two don’t have a sense of humour

ladybird??? or gypsy rose???

Let you off then

You and your neighbour both need to contact your supplier. Let us know what they say.

Its k I know I'm not an electrician. Just trying to figure this out as we have been trying to solve it all day and beginning to wonder if it's a larger issue

That's not HV, just higher than normal LV voltage, what were/are you measuring the Voltage with?

We used a calibrated multi metre for measuring

 

[telectrix]

if the supply voltage is > 253V, it's out of tolerance. contact DNO ( SP Energy, whoever)

It may not be your next-door neighbour but the house a few doors down that is on the same supply phase as you that has the problem as well.
We were doing a school a few years ago where the emergency light fittings kept on burning out this was due to the voltage at the fittings being 250v+ we contacted the lighting manufacturer who said that the fitting gear was up to 250v so got in touch with Weston Power who altered the windings at the sub-station.

How recent was the last calibration?
Ideally you would check the test results with another calibrated meter to double check the results.

Anything over 253V is above the normal limits and could indicate a problem, there are certain faults which can cause the voltage to rise at some properties and fall at others which can be very dangerous, you should contact your DNO and report the fault.

One thing which has been known to cause this problem is the theft of the copper N-E from a substation.

the DNO usually react to potential over and under voltage situations quickly and often install recording equipment at the head for 24-48 hours to confirm.

Basic voltage in uk is 230 +10%-6%, there will be many plug sockets marked as being able to cope with the old standard 240. No problem they will cope easily with the new lower supply voltage. Test the actual supply voltage then as davesparks ,anthonybragg and TonyMitchell said.
