Electricity Meter flashing light
lemmy
has a red light wich is flashing slowly. Plus the LCD display is
flashing between 8888 and the current reading. Does anyone know what
this signifies?
Colin Wilson
The flashing red light indicates usage, and somewhere on the meter
will probably be a reference to xxxx flashes per kWh
The 8888 is simply a test pattern to prove the meter has all the
display segments working correctly.

The light flashes once for each 1W/hr consumed (ie 1000 flashes per kW/hr)
> Plus the LCD display is flashing between 8888 and the current reading.
Shows that all the segments of the display are working and thus the
numbers shown are correct. No confusion between say 8 and 0, or 7 and 1
etc.

Hmmm which is the most likely :
a) Test pattern to show that the display is correct.
b) Copper that knows anything about electronic electricity meters.

No, I don't think so. See the reply from Colin Wilson.

You mean the one where he typed, "The flashing red light indicates
usage, and somewhere on the meter will probably be a reference to
xxxx flashes per kWh"?
While it may or may not be 1000 flashes per unit, the light flashing
certainly does indicate usage.

Err, yes, and my reference to CW's answer made it quite clear that I wasn't
disputing that the light flashes to indicate usage.
What I was disputing was the statement that the light flashes once for
every watthour. It is an erroneous statement that might mislead others. Or
are you suggesting that we should collectively turn a blind eye to
misinformation?

The meter in the office is labelled "1000 imp/kWh". I assume that
"imp" stands for impulses, AKA flashes.

And the one here at home is labelled 800 imp/kwh. Which proves my point
that the earlier statement that the meter flashes once for every watthour
consumed is misleading. It *may* do, but other calibrations exist.

Hi there
It would seem to me that these meters are flashing their LED to indicate Watts
and not Watt/hours.
If my (1000imp) LED flashed 1000 times in an hour then that is indeed 1KW/hr
but what if it takes 2 hours to flash 1000 times? or only 30 minutes? Is it
just me or is everyone else wrong?

passed, for some definition of "unit" (not necessarily 1kWh).

It the number of joules used by a 1kw load in an hour, or a 2kw load in
30 minutes, etc.
You will get 1000 flashes for each kw hr of energy used whatever time it
takes.
You can determine the actual watts by timing the flashes if you want or
count them to see how much energy you have used.

hours or 2kW for 0.5 hours, it is equivalent to taking 1kW for 1 hour.
Yes time is used in the calculation, but the final result is not time
dependent , it is simply an amount, which could be spread over any
length of time. To see this, simply convert kWh into Joules ... again a
simple amount of energy, but no mention of time.

My own feeling is that it does, as indeed this article and other
articles would have us believe:
http://www.efm.leeds.ac.uk/CIVE/CIVE1400/Section5/dimensional_analysis.htm
John Rumm
effect power multiplied by time.
Power is the rate of flow of energy - i.e. energy divided by time, so
with kw h you are getting:
energy
------ x time
time
Two times cancel out, and leave you a measure of energy with no rate of
use component.
Bob Minchin
dimensionally watts= energy/time
again dimensionally, watt.hrs = (energy/time).time = energy

flashes actually means 1000 watt-hours have been consumed. If it takes 2
hours or 30 minutes or any other period for 1000 flashes, 1000
watt-hours have still been consumed, but not at the same wattage.
The unit is watt-hours, not watts per hour which doesn't make sense.

I.e. in the UK when the sun rises on a sunny summers day the power
output of all thjose solar panels rises at a peak of about 3GW per hour..
