This paper describes switching overvoltage generated during transient state in 22.9kV combined distribution systems. For analysis, distribution overhead line, underground cable and surge arrester are modeled using EMTP/ATPDraw. Simulation results show switching overvoltage according to various kind of parameter and systems such as closing angle and cable length.
