Abstract： - An automatic verification system for ultra-high voltage ( UHV ) gas-insulated switchgear( GIS) current transformer is researched to solve the onsite verification problem of UHV current transformers. The system mainly consists of an intelligent power supply, a large capacity current generator,a reactive power compensation device and a standard current transformer. The intelligent power supply has the functions such as power electronic power supply and electrical power supply series output, circuit parameter calculation, reactive power compensation control and error verification. The large capacity current generator is designed by the method of series and parallel connection of the primary winding. The multi-combination reactive power compensation device is designed using the parallel compensation of the primary and secondary side. This system passes the system test of provincial measurement institution and onsite verification of State Grid key UHV project current transformer. The results show that, the verification system realizes accurate measurement of primary circuit parameters of UHV GIS current transformers, electriferous automatic switching of reactive power compensation device for current generators and automatic error verification, and that ensures the accurate and quick positioning of 7200 A high current verification point and 15 A small current verification point,and reduces the capacity requirements of the onsite power supply and the current generator.
