Summary of Fault Line Selection for Single-phase Grounding in Small Current Systems
2020At present, fault line selection theory of small current grounding system mainly focuses on solving the reliability problem of urban power supply system. There is little research on the line selection theory of mine distribution network, but single phase ground fault in mine distribution network will cause more harm.

Single phase to ground fault location based on phase of zero-sequence current
2013 IEEE International Conference on Information and Automation (ICIA), 2013With the continuous development of society and the improvement of people's life, people are increasingly concerning about the safe operation of the power grid, and single phase to ground fault of distribution networks is one of the problems. Because more branch of distribution networks and complex structure, the traditional methods can't achieve ...

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
