摘　　要：随着智能变电站快速建设,常规互感器测试方法已不能满足智能变电站互感器现场验收测试要求。介绍的低压升压法和短路升流法,以变压器为主体,通过一次加压模拟智能变电站投运过程,经过原理和向量分析,全面测试验收智能站电压和电流互感器的各种参数,并且方法简单、操作方便、快捷,大大提升了智能站互感器测试效率。With the rapid construction of smart substations,the conventional transducer testing method can’t satisfy the field acceptance test requirements for smart substation’s transducers. This article introduces a voltage-boosting method and short circuit current- boosting method,which,taking the transformer as the main body,simulates the operation of the smart substation through voltage boosting. By means of principle and vector analysis,a complete series of tests are made on various parameters of the voltage and current transducers of the smart substation. Furthermore,this testing method is simple,quick and easy to operate,and can greatly improve the testing efficiency for the transducers at the smart sub-station.
