Abstract

In order to improve the accuracy of zero sequence current measurement

the method based on three-phase sequential connecting Rogowski coil was presented

simulations and experiments validated the accuracy of Rogowski coil.Based on the complementary of the steady-state zero-sequence current amplitude and phase comparison method and the transient zero sequence current amplitude and phase comparison method in fault line selection

a combination faulty line selection was provided.The method had higher sensitivity and reliability

specially

when the zero sequence current was small during the high resistance grounding.
