Smart meters

Kelly Marie Angel

Hi about 3 weeks ago I was forced into having a smart meter they needed to replace the gas meter because it was in a dangerouse state fair enough I won't argue about that. But they also changed my electric meter now I've just measured the current in the phase tail to the meter and it works out as about 200mA more than the calculations  based on my wattage consumption ie watts divided by 240 should give amps now is the 200ma likely to be the meters consumption or just something with a less than unity PF? Also do smart meters measure kilowatthours like a proper meter or do they measure KVarh

    Could well be power factor in my view. I very much doubt that the electricity meter consumes that much.

    A capacitive power factor can result from loads that derive an extra low voltage internal supply from the mains by a capacitive dropper.

    An inductive power factor can result from discharge lighting, lightly loaded copper/iron transformers and electric motors. Errors in measurement can result from the actual supply voltage being less than 240 volts. 100 watts at 220 volts will be a greater current than 100 watts at 240 volts. Or you clamp meter may be inaccurate at low currents.

    Smart meters do measure true KWH and not KVARH
