Abstract |
This paper presents the voltage characteristics of the various faults after lightning surge hits the overhead grounding wire close to the transformer's secondary side. Based on the modeled distribution system, the cases of the various faults occurred by lightning surge are simulated using EMTP/ATPDraw and maximum overvoltage and RMS voltage according to the distances from the transformer are investigated. As a result, it is seen that the voltage characteristics of faults caused by lightning surge is different depending on the fault type and the voltage characteristics can be used to detect the fault type caused by lightning surge. |
