Discussion on Small Current Output Technology for Verification Apparatus of New Type AC Electrical Energy Meters
OIML R46 is an international recommendation issued by the International Organization of Legal Metrology (OIML) in 2012 for new type active electrical energy meters. As a member of OIML, China must adopt and implement R46 in the follow-up verification of watt-hour meters. However, the existing calibration equipment of watt-hour meter can not complete the verification of small current point in R46. In this paper, the small current output technology suitable for R46 new type watt-hour meter verification device is discussed, and the hardware design and software control are introduced, and the feasibility of this technology is verified by actual test.
