A high accuracy standard for electricity meters

Advances in electronic metering have ushered a proliferation of claims from vendors that their meters are accurate to some small, random, un-documented number. Statements of this sort are misleading and undermine the standards that were developed through the deliberation and input of all parties concerned with electricity metering. The author would set forth that a new standard which encompasses the capabilities of modern electronic meters be approved. A new accuracy class of 0.1% would require manufacturers to test meters under all approved test conditions and would give buyers a current standard to use when evaluating meter technologies. The market acceptance of high accuracy instrument transformers is a clear indicator that utilities see the necessity for high accuracy equipment at large power transfer points on the electric system.
