Propagation of the wave front on untransposed overhead and underground transmission lines

The propagation of the switching surge wave front on multiphase power lines was investigated by modal analysis and conventional Fourier Transformation. A 500 kV untransposed, three-phase transmission line, for which field test results were available, was chosen as a test case. Phase A of this test...
