The aim of this research is to quickly and accurately identify fault line characteristics through a comprehensive investigation into the distinctive attributes of single-phase earth faults, thus improving the dependability of the electrical power supply. Initially, the review focuses on ground fault in single-phase systems within low grounding system for current, summarizing study’s commencement and significance. Secondly, The essential features of the low grounding system for current are further dissected, with particular emphasis on the behavior of neutral without grounding and earthing system for arc suppression coils methods during single-phase earth faults, and the steady state and transient capacitance under fault are analyzed in detail. In the third part, the transient and steady-state electrical properties of single-phase ground connections faults within the low grounding system for current are thoroughly examined, and the simulation model of the system is successfully established and analyzed in detail by using the Simulink simulation platform of Matlab software.
