| Abstract: | The basic comment on electronic current transformer,including Rogowski coil current transformer and optical current transformer,is presented. It is obvious that the optical current transformer excels the Rogowski coil current transformer in respect of dynamic measurement quality. The practical technologies have been formed for the two kinds of electronic current transformer. The electronic current transformer is significant for improving the accuracy of dynamic observation of power network and the reliability of relaying,and is the fundamental of the construction of digital power system. |
