Analysis of Single-Phase-to-Ground Fault Generated Initial Traveling Waves

2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005
Analysis of fault generated traveling waves is the base to implement traveling waves based protection and fault location. However, the structure at fault point is not asymmetrical under single-phase to ground fault condition in multi-phase power system, so that traveling waves analysis method of single circuit can not be applied.

Single-Phase Ground Fault Detection of Small Current Grounding System Base on Wavelets Analysis

2013
In order to improve the accuracy of line selection and reduce the possibility of single-phase ground fault in small current grounding system, this chapter solved two key problems including exploring the fault information of transient signals as much as possible and extracting the characteristic component of transient signals. This chapter proposed that

Predicting Damage from 277-V Single Phase to Ground Arcing Faults

IEEE Transactions on Industry Applications, 1977
Laboratory tests of arcing faults trapped between a corner of a simulated steel housing and single or multiple bus bars were found to be reasonably reproducible and caused relatively consistent burning damage. Single phase 277-V arcing fault tests using spacings of 1 to 4 in from bus bars to ground at current levels of about 3000 to 26 000 A indicate ...
