| Abstract: | The current protection is divided into two types that are definite time lag and inverse time lag.The application of definite time lag current protection has already been familiar to us.The conception of inverse time lag current protection is also very simple,but it has some skills and methods when the curves are chosen and undetermined parameters are ascertained,which are introduced in this paper with the examples of inverse time lag zero-sequence current protection of mating line and negative-sequence inverse time-delay over-current of generator. |

| Keywords: | inverse time lag zero-sequence current negative-sequence current |
