Hello,

The past few weeks I have become aware of the house lights flickering
very slightly. I'm pretty certain it is not my eyes / imagination as it
is not something I have ever noticed in other buildings.

The effect is VERY slight but regular (approx 40 times per minute). It
is something I am aware of from time to time (so who is to say whether
it is intermitted or I just don't notice it). As i said, the effect is
very slight and it applies to lightling plugged into the mains sockets
as well as ceiling lights.

I have checked with my neighbours, but they have not noticed any
problem. Is this something that can be easily detected with the proper
equipment?

TIA

When I worked in Wells we sometimes noticed this phenomenon. I was told
that the premises were near the end of a national grid line and shared
the line (we're talking high-power here) with a factory that made
supermarket trolleys. They spot-welded all the joints on each trolley
in one go and the instantaneous load dipped the mains voltage just
enough to cause a very short but noticable brown-out.

Possibly this is more/less noticable with incandescent lights as opposed
to fluorescent ones. Maybe your neighbours are on a different phase, or
just not as attuned to it as you are.
