摘要: Operations with circuit breakers and switches in power system causes switching surges. Switching surges due to closing reclosing operations could be dangerous for equipment substations. Determining overvoltage level the is important reliability. These representative overvoltages are useful insulation coordination procedure. Due nature of statistical distribution more than one operation needed. This paper present analysis energization re-energization overhead transmission line 220 kV breaker substation kV. The model study done ATP/EMTP software.
