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

The use of phase voltage modules to select the damaged phase in case of single-phase earth faults
Омский научный вестник, 2023 In case of short circuits, the selection of damaged phases always precedes the determination of the damage location. To select the damaged phase, filter selector of the damaged phase are widely used, using symmetrical components of phase currents.
