A new single phase fault location method of noneffectively grounded networks for DA systems
2013
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013)
unpublished
The paper presents a new small current grounding fault location method applicable to distribution automation systems (DASs) using fault transient currents. The faulty section is identified by comparing the degree of similarity of transient currents of feeder terminal units (FTUs) (including faulty line selection device) at adjacent switches. If both transient currents are highly similar, then the section is regarded as the sound section, otherwise as the faulty section. The paper also analyzes
