Research on the Testing Method for the Transducer of the Smart Substation

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.
