| Abstract: | This paper analyses the influence of transition resistance on distance relay's measured impedance when single- phase to earth fault and phase to phase fault happened.In order to remove this influence,this paper puts forward a compensation algorithm by collecting electric currents and bus voltages in both sides of the faulted line at the same time. |
