Still in trouble.

[devonwoody]

Had a bad day yesterday, and in addition I telephoned our local electricity board at 9pm last night and asked if there was a power reduction problem because our TV screen was not showing a full picture and our living room lights were dull.

An engineer arrived 20 minutes later and checked out the incoming voltage which was OK at 244 volts.

So can anyone please tell me what this means because lighting is still poor this morning and TV screen has not returned to normal.

Hi Devon,

but the power reduction is in the all house or in living room only? I've studied for electrotechnical matter and by my experience sometime you can have 240 vac at one point of a generic circuit but the same value cannot be at another if between there's a point with high electric resistance.
With this I wish to say that if the engineer has measured the voltage at the point in which arrives the electrical supply and you have a poor contact into the following switch all the voltage or a part of this, when a current is needed, can fall in that point.

My advice is check the screws of the switch are tight.

If the engineer has measured into the electric plug, for now, I don't know..

I hope this help

Electrical resistance is most probably the cause start at the distribution box operate all switches especially the main box switch it would seem the fault affects both the lights and the ring main then its wiring or two separate faults so get a electrician.

What protection do you have? (No not that sort [-X ). Earth leakage trip? RCD? Did he measure incoming volts on their side of the meter? Or on your side of the meter?

It sounds as if you have a bad connection (ie high resistance as others have said) somewhere in the main feed since it affects both lights and the TV (which is off the ring main I assume...unless you've plugged it into the light socket :wink: )

You do need to get this fixed ASAP (like as in NOW). Do NOT run any high wattage items ...not even your woodwork tools. Not even a fan heater. Not even your cooker/microwave/oven.

The reason is simply this...if you have a high resistance then the more current that you draw the hotter this high resistance point is going to get. Best case scenario...charred wiring/connection whatever which may (probably will) need replacing..

Worst case scenario - FIRE

Good luck

If you feel handy with a meter then you can do your own fault finding to try and find the high resistance point. If you do call me on my mobile and I'll talk you through it

He checked their side of the meter and also took the main company fuse out and replaced and did a check there.

Hope its owing going tobe a screw loose somewhere.

Seem to be out of trouble.
An electrical contractor came in and could find no Hi resistance, thought it was most probably light bulbs need changing, and my TV sets are old so most probably the tubes are going up the spout.


However I must thank forum members for their replies and I might add going the extra mile and providing me with their telephone number and giving further advice.
