Abstract
The lightning surge and switching surge could be injected to the underground distribution line through the riser pole in the mixed distribution line of overhead and underground. These surges travel along the cable and are reflected at the end of cable. It can be doubled and affecting underground distribution facilities. It was made a underground distribution model representing KEPCO's distribution system. It was measured propagation characteristics by applying lightning surges to this underground distribution model. Meanwhile, this system was simulated with ATP-EMTP and compared these real test results md tuned up the EMTP parameters. EMTP simulation results showed that accord with real test result by adjusting the cable insulation permitivity, arrester characteristics, surge wave shape.
