News | Electronic energy meters’ false readings almost six times higher than actual energy consumption | University of Twente – Enschede
For quite some time now, rumours have been rife about electronic energy meters that give excessively high readings in practice. This prompted Prof. Leferink to investigate electronic meters, to see whether they can indeed give false readings. Together with co-workers Cees Keyer and Anton Melentjev from AUAS, he tested nine different electronic meters in this study. The meters in question were manufactured between 2004 and 2014. The meters were connected, via an electric switchboard, to a range of power-consuming appliances, such as energy saving light bulbs, heaters, LED bulbs and dimmers. The researchers then compared the actual consumption of the system with the electronic energy meter’s readings.
