- Abstract:
- The measurement of the electrical energy and its billing for tax purpose are of great relevance. In the past a scarce attention was given to issues as the calibration and the traceability of the electrical energy meters (EEMs), so that, at least in Italy, more than 30 millions of EEMs operate and put a tariff without proper metrological characterization. This situation is caused by both the absence of specific laws and the high cost related to the traceability process. In this ambit, a new European Directive on measuring instruments (MID) was introduced in 2004 with the aim of providing a high level of metrological protection in order that any party affected can have confidence in the result of measurement. In Italy the MID was adopted by a legislative decree and imposed that: (i) each active EEM put into service has to be kept in test for a period for verifying its operating; (ii) after the test period, with positive result, the meter has to be calibrated at least twice in the year. The paper proposes a discussion about the issues of active EEM calibration and the analysis of requirements of the MID. Finally, the design of a device that may solve the problem of the traceability to national standards in easy and economic way is reported.
