Abstract

The paper presents measured results of the corona wave-deformation on a test line with various boundary conditions corresponding to a substation. The measured results have shown an increase of the phase-wire voltage at the receiving end under a certain boundary condition, while the ground-wire voltage is always decreased by the corona wave-deformation. The phenomenon is theoretically investigated, and it has been made clear that the increase is, in principle, caused by heavier attenuation of a traveling-wave on a ground wire than that on a phase wire, and the negative reflection of the traveling-wave from the ground wire to the phase wire. The condition of the voltage increase has been theoretically derived
