Abstract :
For calibration for three-phase power/energy comparator with class degree of 0.01, a standard equipment with the uncertainty better than 0.01% will be essential. In this paper the relevant work in NIM is reported, including composition of the equipment, influence among phases and comprehension of uncertainty.
