Strange Meter Readings (30 min AMR)

AncientMariner
With no booking for room hire and thus no income, I have been trying to reduce electricity consumption in our village hall. I cannot just simply switch off at the isolator, since there is another user who has access for an office.

This morning 09:41 looked at the consumption graph for Thursday 2nd April and was pleased that I had apparently reduced it by more than half from the previous days.  Then looked again this evening and I hadn't!  I thought I had seen similar yesterday, so this time copied the screen to a file:

Confusing, to say the least!

    Dodgy software!


    I measured the three phases, neutral and earth currents this morning with just the emergency lights internal chargers on, two permanently on outside low energy lamps and the fire alarm system.

    There may also be usage in the office that is rented to an outside firm.

    L1 0.235A  L2 0.98A  L3 1.15A  N 0.988A  Earth 0.175A (TN-C-S from cable sheath.

    This will have been less than Thursday's graphs, since found a fridge freezer running in the kitchen containing just two small bags of frozen fruit… That is now off!

    I obtain the graphs from SSE Business Electricity "Clarity" website https://www.ssebusinessenergy.co.uk/smart-metering/clarity/ so should be accurate. Although last July there was a slippage in the day of the week versus the date, which was confusing!

    With electricity usage varying day to day, week to week, depending upon hirings, I have never paid a lot of attention to the graphs, other than querying our manager when there were strange spikes late at night. It is only since our hirings have ceased so that what is left is the base load and from the graphs seemed somewhat high. Especially with no hiring income.

    Last night I dug out the monthly bills and found that contrary to what I had thought, the billing period is the actual month, not a month between the dates the bill is produced. The reading dates not being that clear like on a domestic bill. So with that knowledge soon found that for the three months ending 1st Jan, Feb & March, the "Clarity" Total kWh shown in the top LH corner for past history graphs was twice the correct figure from the Bill.  

    So our consumption for yesterday Saturday 4th is now showing 8 kWh. I am hopeful that today's consumption will be less, since besides the fridge freezer being on until mid-day there was a peak in usage due to my wife using hot water from the under sink heater to do some cleaning whilst I was fitting a new gents urinal flush controller.

    Must admit that we had issues last year with our gas graphs since these too are in kWh and the figures bore no resemblance to reality, since we appeared to be consuming gas at the rate of a small power station. (We have a 5 MW gas fired power station about a mile away.)  Apparently they had made a mess of the conversion factor to convert cubic metres to kWh…

    The above makes me wonder how many of their consumers use Clarity, I seem to been "selected" as the Beta tester…..


    My next job? An email to SSE.
