One kind of transmission line lightning traveling wave test system

Lightning one kind of traveling wave transmission line test system, a lightning transient electromagnetic and movable mold apparatus composed of intelligent transmission line monitoring apparatus; to lightning and power transmission line model, the ground tower and tower model and the insulator body model, the tower oblique member is divided into sections, and the main timber section crossarm section, taking into account the transmission line insulators and lightning line factors with a wave impedance corresponding to the self-impedance and mutual impedance, since the admittance, and the like, and an inductor transadmittance simulated lightning strike Construction transient equivalent circuit. The latter in turn cascade A / D converter by a current or voltage sensor, a microcontroller and a display or oscilloscope composition. This system was added at different locations inrush current, the measurement signal lines and wire distal lightning, the lightning can be analyzed during the propagation of the entire transmission line, based on the analysis, optimization of transmission lines and substations weakened segment line lightning lightning protection device.
