Single-phase switching offers many benefits, which increase in value at higher transmission voltages. Among them are improved transient-stability transfer limits, reduced switching overvoltages, and reduced torsional stresses on turbine generators during fault and load-rejection conditions. Analysis of a recent set of 27 full-scale phase-to-ground staged-fault tests on a 765-kV transmission line by American Electric Power Corp. was conducted. These test results can apply to all existing and proposed HV and EHV transmission lines. Understanding of the test results has reduced concerns over harmonic components in the secondary arc current.
