More Smart Meter Problems

smartmeter_-_low_resA Dutch study by the University of Twente, in collaboration with the Amsterdam University of Applied Sciences, discovered that energy saving light bulbs, LED bulbs and dimmers can give false meter readings that are 582 per cent higher than they should be. Professor Frank Leferink of the UT estimates that potentially inaccurate meters have been installed in at least 750,000 Dutch households.

Five of the nine smart meters tested gave readings that were much higher than the actual amount of power consumed – up to 582 percent higher. Two of the meters gave readings that were 30 percent lower than the actual amount of power consumed.

“We were flabbergasted by our results,” said Professor Leferink. “I believe the problem surrounding the accuracy of smart meters has been under-estimated and more research is required.”

The study was published in the scientific journal IEEE Electromagnetic Compatibility Magazine.
