The IEEE Electromagnetic Compatibility Magazine recently published some research showing that under certain laboratory conditions with extreme levels of high-frequency interference, certain electricity meters displayed inaccurate measurements. Only meters equipped with Rogowski coils or Hall Effect sensors were affected. These are specific metrology components that are not common to all meters.
There is currently no meter containing either Rogowski coils or Hall Effect sensors installed as part of the GB smart metering rollout. There are no meters containing these components currently under development for release as part of the smart metering rollout.
