摘　　要：针对整体检定装置特点,介绍了两类互感器校验仪误差测量方法。从结构上看,一类是常规互感器校验仪,具有工作回路电流(或电压)和差值电流(或差值电压)输入端子,可依据规程线路测量其误差。另外一类具有标准电流(或电压)互感器与被检电流(或电压)互感器二次回路输入端子,不具有差值电流(或差值电压)输入端子,通过变换常规线路,采用电流并联叠加和电压串联叠加方式,解决了此类互感器校验仪误差测量问题,并从理论上分析了方法的可行性。Two types of transformer calibrator error measurement methods are introduced,one type is a conventional transformer calibrator,which has a working loop current (or voltage)and a differential current (or differential voltage)input terminal,and can measure its error according to the regulation circuit;the other type is the one with the input terminal of secondary current of standard current (or voltage)transformer and detected current (or voltage) transformer,which does not have a differential current (or differential voltage)input terminal.By transforming the conventional line,parallel circuit with current and series circuit with voltage are adopted.The problem of error measurement of such transformer calibrator is solved,and the feasibility of methods is theoretically analyzed.
