Losing power to house post meter upgrade??

[lurch]

got called back to a rewire I completed 5 years ago. Customer reported intermittent loss of power across the house. I have a swa sub main from a 63amp switch fuse to the CU. I have checked all terminations at CU and switch fuse . . . . all good. Have thrown thenmain switch 4-5 times to see if it is faulty but all seems good.

Customer has advised new meter was installed 5-6 weeks ago . . . Ive given tails a good tug to see if there is anything amiss, but nothing to suggest any issues.

Has anyone come across a faulty meter that could be causing the issue?

Thx in advance.

What's the duration of the power outages and how often has it happened? Is there any kind of pattern or do they seem random in their time of occurance and their duration? What did the customer do to get the power back on again?

2-3 mins. max 5 mins. outages are becoming more frequent . . . 1 or twice last week, now 2-3 times a day. no pattern that is obvious. customer checked mcbs, RCDs and nothing tripped. .. . power is reinstating itself. . . suggests loose connection or faulty component somewhere .

PME 100amp BS1361

If you just want to prove it's not a warranty claim on your CU replacement I'd maybe install a temporary LED pilot lamp on fly-leads (with a small inline fuse) across the incoming supply at the CU. If the LED goes out when the next power fail happens then it indicates a meter or DNO fault.

You could obviously do the same with a PQA or logger if you have access to one....

Keep an eye on consumption ,some meters have overload shut off !

Really? Who installs those? Is that on usage or over-current?

With the OP's power coming back on,these meters must have a re-closing device,which is going to require a re-write of certain legislation...

Re-closing device,(... require a re-write of certain legislation...)

Sorry my mistake !
Good point , just putting overload protection hidden in new places out there .
--Cannot be the case today ,because they don't re-close ,without user action--
..and beep their head's off ..
