Abstract :
Transient voltage increase in electricity networks is of great importance due to security of devices and insulation considerations. One of the factors which results in transient voltage increase is connection switching. This overvoltage cannot be measured and recorded via usual measurement devices. In this study, possibility of using power quality analyzer for recording and measuring transient overvoltages is studied. To this end, switching in a 20KV electricity network in Imam Khomeini airport city is simulated using EMTP-RV. Then, real switching is performed and overvoltage is measured by power analyzer. Then, these two methods are compared.
