Discuss Appliances in single phase property damaged by 415v in the Electrical Engineering Chat area at ElectriciansForums.net

I wouldn't be surprised if the other 2 appartments have got as yet undiscovered failed / faulty appliances.
Possibly even others beyond the 3.

They could all end up individually paying to have items fixed when they shouldn't be.
I'm going back tomorrow I said drop off some more light bulbs for her and I'll try asking them. How likely is it to for them to successfully claim for damage from NPG?
 
Yes, she rang them first and they told her to isolate the supply and call an electrician. At that point it wasn't clear what had happened, they could have reasonably just thought it was a faulty light fitting and nothing to do with them. When I realised what the problem was I phoned back but said they wouldn't treat it as an emergency as long as the supply was isolated, and call again in the morning. So no, she had no power overnight which is bad, but she was just relieved to go to bed knowing the light wasn't going to carry on burning!
So what did you identify the problem as?
As to the DNO response I would have certainly got the name of the person you spoke to as leaving a vulnerable old lady without power overnight is an extremely calous action and worthy of some retraining, I think I would have been asking to speak to the duty supervisor

I assume when you say them you are only referring to your customer, I don't think they have any chance of a claim due to the way it was reported to the DNO and the response they gave it

It may well be worth getting her to speak to the neighbours. If 3 separate apartments have had damaged appliances - along with your test result that night, I would think they would find it hard to argue that it was nothing to do with them (assuming there isn't a BNO involved).

At the very least I would put something in writing to the DNO - from the customer ideally, but with your 'site report' included (Just a description of your actions, on business letter headed notepaper.)

I'm surprised that they thought an elderly lady would be fine without any power overnight - at the very least a complaint in writing will make someone look at the call logs, etc.

Not sure if her insurance company might be worth mentioning this to as well (assuming she has one and was going to claim( - they might well be interested if they can offset any of their claim onto the DNO.

The supply voltage was too high. Yes I agree it was bad of them.

I meant anyone that's had equipment damaged. When I spoke to them I made it very clear that I was getting 415v at the supply.

Ironically I had just finished sending an invoice tonight to the DNO for an exact same situation. It was you Snowhead who replied to my (similar) query a, few weeks ago and you mentioned your son got compensated from DNO for damages he suffered.
I had no issues when I contacted them. They achknowledged liability and simply asked for a list of damages and bank details. I think it would be rare if there was no record somewhere of a power outage. In any case, from what I have read here there certainly appears to be sufficient circumstantial evidence

Do you have any idea why the voltage would be so high?
 
Possible broken neutral, I couldn't investigate any further as it's the DNOs domain.
It's quite clear from your responses that you were totally out of your depth with this fault and lack some very basic knowledge of the electricity distribution system and what causes faults like this to occur

So instead of getting personal, how about you tell us your theory!

Not quite sure how I can be "out of [my] depth" when the fault is on the supply side and acknowledged it's the DNO's responsibility and contacted them.
