Calibration Reliability

All over the world, large-scale replacements of installed base kWh-meters are taking place in smart metering projects. In most of these locations, the majority of the installed meters are electromechanical meters, with proven long standing technology. Financial risks are huge, as replacements are undertaken in large-scale accelerated projects, rather than over longer-term, life-cycle substitutions. Utilities require certainty on the expected lifetime of new meters and are requiring meter manufacturers to independently test and certify the reliability of these meters. For this purpose, a number of standards have been developed.
