Maybe I know of a friend’s, cousin’s, boyfriend’s, aunt, who observed a greater than expected drop in consumed power when 2 Walmart Great Value brand A19 60W replacement LED bulbs were put in a fitting dimmed with a standard old rotary dimmer…. So, you can quite easily build your own powermeter but you need to take into consideration how you measure both the voltage and especially the amperage – any off the shelf CT coil doesn't cut it. electric motors/florescent lighting) since they only measured the voltage and the current draw. I remember one case where the meters didn't take into account out of phase current due to the loads having high impedance/capacitance (ie. I'm not that surprised that new digital meters reports the wrong energy consumption, just imagine all those switched PSU's introducing harmonics and uneven power draw which can't really be measured correctly unless you sample both the voltage and the amps accurately up to a couple of kilohertz The frequency response on CT sensors are usually less than the 8th harmonic (< ~400-450 Hz) which means anything above that are lost. One of the problems with current sensors used in meters is that they are cheap and doesn’t have the frequency response to handle some high-frequency loads. It is worth noting that there is contradictory research published by “the European voice of the providers of smart energy solutions” that maintains that “there is no reason to question smart metering technology”. Still, we wouldn’t blame you if you wanted a second opinion. “The experimental results show that static energy meters can be pushed into faulty reading (positive and negative) if sufficiently fast pulsed currents are drawn by the consumer” “The reason for faulty readings appears to be the current sensor, and the associated circuitry,” said researchers. (Certainly makes us want to keep a close eye on our electric meters.) ![]() Tests with uncommon results were repeated several times and the results were within a few percents of the original.” Moreover, “The greatest inaccuracies were seen when researchers combined dimmers with energy saving light bulbs and LED bulbs.” Not constrained to energy saving light bulbs, the inaccuracies are, ironically, tied to devices with integrated energy saving features. Their results? Well, “results varied wildly, with some meters reporting errors way above their disclosed range, going from -32% to +582%. Moreover, the researchers tried to reproduce standard household energy consumption patters rather than focusing on stress tests. With experiments lasting for six months, the researchers tried to focus on meters representative of those commonly used in the Netherlands and manufactured between 20. Not ones to disappoint, the scientists have found consistently false readings that in some cases are 582% higher than actual energy consumption. What is 4Chan? Ive never heard of 4Chan, please explain in great detail.A group of Dutch scientists have been testing out some of today’s “smart” electrical meters to check their accuracy, among other things.
