Research and Analysis of Small Current Grounding Line Selection System
Journal of Physics: Conference Series, 2022 Abstract In the small current grounding system, because the short-circuit fault of single-phase grounding accounts for more than 80% of the total short-circuit fault, the selection of single-phase grounding fault line is still the main problem in electrical engineering.

Simulation and analysis of single-phase grounding fault in small current grounding system
Journal of Physics: Conference Series, 2019 Abstract The characteristics and distribution of single-phase grounding faults in small current grounding system are not easy to capture, and it is not easy to collect and cover all possible situations in operation site. This paper builds a fault simulation model of distribution network based on PSCAD.

Research of Single-phase Grounding Fault Simulation for Small Current Grounding System
DEStech Transactions on Environment, Energy and Earth Sciences, 2017 Our country generally uses small current grounding system (the neutral point no direct grounding system). Due to the fault current is too small to identify. So the distribution network operators have been plagued by this kind of fault line selection accuracy. This research establishes simulink model to analyze the fault of single-phase grounding system

A Review of Fault Location Methods for Small Current Grounding Systems
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Small current grounding system is mainly used in China’s distribution network. When single-phase grounding fault occurs in the distribution network, it is important to quickly and accurately select the fault line and locate the fault section to ensure the safe and stable operation of the system. In this paper, the fault location
