Abstract

The safe and reliable prejudging device for open circuit in the secondary side of current transformer has been developed. On the basis of explaining the process and defects of the traditional operation, the paper designs a schematic diagram of prejudging device. The suitable values of the shunt resistors have been obtained from lots of calculation and analysis with the safety precaution and approach designed at meanwhile including the components selection and the design optimization. The test results show that the device could well prejudge the circuit open in the in-mending section of the circuit at the secondary side of the current transformer.
