EMC Testing of Electricity Meters Using Real-World and Artificial Current Waveforms

In 2015, the energy measurement of some static electricity meters was found to be sensitive specific conducted electromagnetic disturbances with very fast current changes caused by highly nonlinear loads, leading meter errors up several hundred percent. This article describes new results on compatibility (EMC) 16 different from all over Europe when exposed real-world disturbance signals. Those test signals were obtained household appliances and onsite measurements at metered supply points Europe. The show that also interference recorded can cause as large percent, even for pass present EMC standards. unambiguously demonstrates immunity testing standards do not cover most disturbing occurring in daily-life situations due increased use electronics. Furthermore, enable adoption potential waveforms future testing, artificial constructed based using a piece-wise linear model. These demonstrated similar those original real-life they are representing, showing suitable candidates improved standardization testing.
