Transient based Single Phase to Ground Fault Distance Computation
2009The subject of this work is location of single phase to ground fault in medium voltage distribution network. The considered distribution network can be grounded or isolated and normally is in radial operation. The fault location is based on the fault generated low frequency transient signals of current and voltage of faulty phase measured in the supply

Control of Smart Transformer Under Single-Phase to Ground Fault Condition
IEEE Transactions on Power Electronics, 2020In low voltage (LV) electric distribution grid, the continuity of power supply service is degraded by various grid faults. Even under single phase to ground faults, the continuous operation capability of healthy phases is also limited. The smart transformer (ST) can establish each phase voltage independently and thus can switch the operation mode from ...

Analysis of Single-Phase-to-Ground Fault Generated Initial Traveling Waves
2005 IEEE/PES Transmission & Distribution Conference & Exposition: Asia and Pacific, 2005Analysis 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
2013In 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, 1977Laboratory 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 ...
