Abstract :
The transient current measurement of the power system by an improved ac/dc current transformer is developed. The transient performance details and calculation formulas of the transformer are analyzed and derived. The important design bases for transient current measurement of the current transformer used to the power system are given. Testing results show that the transient error of 5000-A improved ac/dc current transformer is less than 1 percent, while the error of conventional transient current transformers is 5~10 percents and even much more
