Research on the Damage Characteristics of OPGW by Lightning Current Component Based on COMSOL
The damage of the optical fiber composite overhead ground wire (OPGW) seriously affects the safety and stability of the power system. In order to study the impact of lightning current on the OPGW damage, COMSOL Multiphysics is used to simulate the local temperature of the lightning strike. The results show that the A component of lightning current has little effect on OPGW damage, which is mainly caused by the subsequent C component. The C component of lightning current is more destructive to OPGW, and the amount of charge transferred is the main cause of damage. The simulation results provide references for future research on OPGW's lightning resistance and mechanical performance.
