| 摘 要： | 针对电能表检验装置在检定中存在的问题，检定负载点太少造成空白点而无法修正；功率因数0．8C和0．25L负载点无法准溯源；忽视对多路输一致性的考核及电工型检定装置电源稳定性不足以检定其监视仪表等，并提出了相应解决方法，文中还给出了未检定负载点的误差计算公式。

| Abstract: | It is the universality in the test of the calibrator for Watt-hour meter that the points of load are too little.In result,the point of load untested can not be modified correctly and the point of load at the0.8C and the0.25L can not be traced to the source.This article put forward the calculating error formula of the points of load untested and bring out the solving way used to test the watching meter on condition that ignore the coherence of multi-route output and the lack brought by the stability of power equipment. |
