Does anybody have any ideas why my friend's electricity supply appears to
reduce in power by the voltage dropping at around 6pm most evenings. The
lights dim slightly and then go bright over a period of about half an hour
on a regular cycle at roughly 5 second intervals. It stops and goes back to
The house was re-wired about 10 years ago to then correct standards. They
lost all power once which proved to be a poor connection within the meter
and persuaded edf to re-wire the meter after a big argument as they wanted
to blame their domestic wiring. That is an unrelated problem and is OK.
About 3 years ago the main wiring in the street shorted out and caught fire
underground in several places lifting the tarmac. The whole street was out
for about a week and generators were provided. This seems OK now and the
present fault seems unrelated and happens at a regular repeatable interval.
There are no switched loads in the house coming on at this time.
Could street lamps starting up cause this type of problem?
Any idea appreciated.
