Electromagnetic Interference on Static Electricity Meters

project summary

Smart electricity meters are currently being deployed by utilities across the EU. However, the accuracy of the energy readings from these static devices is crucial for correct billing, and, recent studies have shown that under certain grid interference conditions caused by modern power electronics, some static meters show significant errors in energy reading, despite the meters being certified according to existing harmonised standards. Therefore, new standardization in static meter testing and verification via development of new instrumentation, test methods and signal processing techniques is needed to ensure present and future customer confidence in static meter energy readings used for billing.
