Smart meters

Kelly Marie Angel over 3 years ago

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

If the meter were really consuming 230V*0.2A = 46 Watts continuously it'd be getting pretty hot given its small size. We might expect that if it were the surface temperature of the case would be tens of degrees above ambient and presumably it isn't. A Watt or two is more realistic for the power consumption of the meter.
