摘　　要：针对组合互感器误差测试采用三相电压、三相电流同时加载存在的弊端,研究了基于电压法的电流互感器和电压互感器二合一测试方法,用一台标准电流电压互感器同时检定电流互感器和电压互感器,接线简便,方法合理,特别适应于组合互感器的现场检定或校准。In view of the disadvantages of simultaneous loading of three-phase voltage and three-phase current for error testing of combined transformers,a two-in-one testing method based on voltage method for current transformers and voltage transformers is studied.The method of simultaneous verification of current transformers and voltage transformers by one standard is simple and reasonable,which is especially suitable for on-site verification or calibration of combined transformers.
