采用S级电流互感器合理配置电能计量装置

Adopt S class electric current the feeling machine reasonable allocation electric power to calculate device with each other

电能计量装置的综合误差主要是由互感器的合成误差和电能表的相对误差来决定的.运用误差理论,着重对采用S级电流互感器,合理配置电能计量装置进行系统的分析.阐述了如何针对不同负荷性质合理地匹配电能计量装置,进而提出减小电能计量综合误差的有效方法,结果表明:此方法能提高计量准确度.

The comprehensive error margin that the electric power calculates to equip mainly from with each other the opposite error margin of the synthesizing of feeling machine error margin and electric power form to decide of.Make use of an error margin theory,emphasize to adoption S class electric current with each other feeling machine,the reasonable allocation electric power calculates equip to carry on the analysis of system.Elaborated how to aim at the different burden reasonably matches electric power to calculate device,then puts forward to let up electric power to calculate the effective method of synthesizing the error margin and carried out to raise the purpose of calculating the accurate degree.
