Induced voltage on objects under six-phase transmission line

This paper presents results of an experimental investigation on voltage induced on objects under a six-phase transmission line due to line switching incidences. In this work, the voltage induced on a vertical receiver and a pipeline due to line energization and de-energization in a six-phase power transmission line system is reported. The research was carried out using a six-phase transmission line mock-up system with ratio of 5/132 kV. The results showed that the induced voltage on the objects is less than 4 kV. In addition the high induced voltage experienced by the vertical receiver was from the left side of the phase composition while the pipeline experienced higher induced voltage from the right side phase composition.
