| Abstract: | The problem of fault diagnosis of a transmission line with a short-circuit or an open-circuit and a contact resistance of arbitrary ralue between lines is studied. Diagnosis pinciples of fault locating and contact resistance evaluating are discussed. diagnosis equations are established. Based on frequency conversion. fault type are differentiated,and diagnosis algorithms are presented.The feasibility of the presented diagnosis method has been proved by computer simulation as applied to practical cases. |
