| Popis: | Lightning stroke is the main threaten to the safe operation of UHVAC transmission lines. The magnetic steel rod method had been widely used as a traditional method for lightning accident and lightning current investigation in high voltage transmission lines. For the application of the magnetic steel rod method on UHVAC transmission lines, this paper proposed a practical and easy improved method of installing the magnetic steel rods directly on the transmission towers. The residual magnetism curve and accuracy verification of the proposed method was obtained through complex steel structure impulse current experiments. The magnetic steel rod location on UHVAC transmission tower was analyzed by the numerical analysis software MagNet. The application results of the proposed method on the first demonstration and test UHVAC transmission line is presented. The obtained datasets after one storm season was analyzed through Electromagnetic Transients Program. It is shown that the proposed method is feasible. |
