Is that church in the bottom end of yeadon by any chance RF? I seem to remember the 1st wiring, not been past for a while, so not seen the "new and improved"

All modern (and old!) poly-phase meters record max-demand, it is often printed on your bills, especially if you exceed your agreed capacity. You will often recieve a monthly penalty fine based on this. Quite often hit the button on the meter to check the max demand, and the last reset of the meter when quoting for jobs where you intend to add significant loads.

When you talk of "all modern (and old!) poly-phase meters", I presume that you're refering to industrial installations? My meter certainly doesn't seem to have any such facility.

How did that work with 'old' meters (like mine, albeit only a few years old) which didn't have digital display screens (and which, I presume, don't 'record' anything)? - was there some sort of additional indicator of maximum demand?

Kind Regards, John.

When I say old, I should perhaps say the last 15 years or so, with digital display, and with a button you press to cycle through screen displays. I was brought up on these!

Ah - a youngster Mind you, I'm sure my meter is under 10 years old, yet, although literally digital (rather than analogue), it does not have a 'digital screen', merely car-odomoter-style electromechanical 'counters'. With such a 'display', and (I presume) no means of 'recording' anything, there wouldn't appear to be any way it could possibly determine or 'display' maximum demand.

Kind Regards, John.

No, they are only available on true electronic LCD screen types, both poly phase and many single phase types.

May take you some pics if I have a moment

For the reasons I gave, that obviously makes sense. However, as I said, they don't have to be very old to not have an LCD screen - my 3-phase one doesn't have such a screen, and is certaibly less than 10 years old.

You don't need to on my account - I know what they look like. Conversely, I could provide a photo of a fairly modern 3-phase meter which doesn't have an LCD scree if you would like to see it.

Kind Regards, John.

I think it is all to do with which tariff you're on, and what your agreed capacity is - If you have a standard 80 TP supply, they generally wont be worried about the maximum demand so much and will likely fit a standard meter. On all CT metered supplies, it would always be a digital type meter, and depending on the supplier, likely half-hourly metering.

That would seemingly be the case in my installation!
