The accuracy of electricity meters can be affected by interference generated by equipment connected in the building that the meter is measuring energy. The nature of disturbing and interfering signals present in typical electricity networks needs to be determined in order to define the accuracy boundary conditions for electricity meters during use.

The extent and type of interference typical in low voltage mains is measured at various meter connection points in various European countries by using digitising equipment and transducers with sufficient dynamic range and resolution to capture the current waveforms in substations and consumer installations typical of those present at metered supply points.

The current waveforms from a selection of consumer products that contain power electronics will be procured are also captured to further identify the signals of waveforms that induce meter errors.
