Impact on 10kV system of inrush current and its preventive measure

The generation of inrush current in the 10 kV grid system and the size and impact on the system is discussed in this paper, according to the cause of the inrush current, how to prevent the harm from the technology and grid structure is discussed and finally the adverse effects of inrush current on the system is prevented from the root causes, to ensure normal and reliable operation of the 10 kV grid system, to avoid protection malfunction and mistaken judgment of handling, to increase reliability of user power supply and security of grid operation.
