| Abstract: | Abstract ：The conventional Class 51）（10P） CT is with transient saturation and residual magnetism, which easily result in malfunction of the difterenlial protection of generator and transfomler. In view of the CT application status, necessities of application of Class TPY CT for the differential protection of 500 kV transformer and unit are desczibed in this paper. Based on the engineering practice, furthermore, the transient parameters of tile Class TPY CT are calculated. These previde design and equipment procurement with basis. |
