A novel approach for distribution fault analysis

This paper proposes to use four different measures: actual values, normalized values, relative values, and likelihood values for power systems´ distribution faults analysis. This paper also discusses the general and local properties of distribution faults. The likelihood measure, based on the local region properties, provides important information for distribution fault cause identification when the fault cause is not known. Tree faults on the Duke Power System are used in this paper for illustration purposes. The proposed measures´ analysis and discussion can be easily generalized for different types of distribution faults in other utility companies
