Performance Evaluation of Surge Arrester Counters in Energy Transmission Lines During Switching: Simulation and Practical Results [PDF]
IET Generation, Transmission and DistributionABSTRACT Switching operations in power transmission lines can cause travelling waves on the lines, generating transient overvoltages. The magnitude of these overvoltages depends on the power system voltage magnitude at the closing time and the trapped charge on the line.
