| Abstract: | This paper analyzes in detail the models of three inverse time over-current curves and presents a algorithm by curve-fitting. The protection has been finished by the algorithm based on Motorola 32-bits Microprocessor. It has been tested that the relay has better characteristic and better practicality worth in engineering. |
