Abstract: An intelligent on-site error calibration system and method for large current transformers at outlet sides of generators in grid power plants are presented in this paper. The system solves the problems of unachieved power supply capacity, unbalanced three phases of power supply, over-capacity required, large volume and big weight of equipment according to the on-site calibration regulations of large current transformers at outlet sides of generators. So accurate, intelligent and efficient error measurement of large current transformers can be realized.
Keywords: large current transformer; generator outlet ; error; on-site calibration; power current transformer
