Dont want to get into smartmeter arguments - I just wondered if anyone knew if asking for a move would get me a take-it-or-leave-it imposition of one.

When you say that you "want your meter moved", then I suspect that you may well mean that you also want the 'service head' (where the supply enters you property, and which contains the 'service fuse') to be moved.

If so, it's not your supplier who would have to move that 'service head' but (possibly at an appreciable cost) the 'Network Distribution Operator' ("DNO") - and since they have nothing to do with providing meters (that is the supplier's territory), it's possible that they would reconnect your existing meter to the moved service head. On the other hand, they might just move the head and then ask the supplier to come and reconnect the (or "a"!) meter. You would need to ask them (the DNO).

Kind Regards, John

...some also question the ability of the smart meters to measure apparent power use over real power...

I haven't looked at the video yet, but my non-'smart' meter can do that - and I assume fairly accurately.

Haven't watched the video, but there have been some incidents of meters measuring rather badly - but that's a feature of the measuring technology, not whether they are "smart" or not. There was a design that got particular stick in the press which used (badly) a Rigowsky coil and over-read badly when fed anything but a nice clean sine wave.

Indeed - even if not totally explicit, that was my point.

It's perhaps rather surprising that one which 'measure rather badly' get through the net, because I imagine that, during development, they are tested with a wide range of possible load/current scenarios, including a range of messy waveforms.

You might think so, but apparently we'd both be wrong in thinking that would be the case.

Yes, I'm not denying that we're probably both wrong in our thinking, but that doesn't alter the fact that I am surprised.

It's not as if the manufacturers of these meters are disreputable tin-pot companies functioning from kitchen tables. Having established that their designs worked satisfactorily with clean sinusoidal currents, they must surely have explored many other possible scenarios?

Of course, very little is impossible, so one cannot expect them to have tested the design with every conceivable waveform, but one certainly wouldn't have expected them to overlook scenarios which were likely enough to be encountered in service to have become a major issue!

Kind Regards, John
