EMPIR MeterEMI project - Report on current waveforms for static meter testing

EMPIR MeterEMI project has released a report on current waveforms for static meter testing. In the report on the selection of recommended test waveforms for meters, in which is explained the rationale for the waveforms and methods used to accurately and efficiently specify these waveforms.  In summary:

  • Most recommended waveforms are based on recordings on-site at real meter connection points. The waveforms have been simplified using a set of parameters, so they can be written down accurately and efficiently, suitable for inclusion in a future standard.

  • All recommended simplified waveforms have been generated on an arbitrary-waveform testbed and several produce gross meter errors on “faulty” meters similar to the original on-site recordings.
