Abstract :
The paper discusses transient induced voltages to a coil system of a magnetic-levitation (MAGLEV) train planned in Japan from an overhead ground wire (GW) which protects the coil system from a lightning stroke. A simplified lumped-circuit coil model is developed based on a two-port theory of an L equivalent circuit of a distributed-parameter line. Its impedances are evaluated from the impedance and admittance matrices of an overhead multiconductor system, which represents a coil, using the EMTP cable constants. The calculated results of transient induced voltages by the proposed coil model agree satisfactorily with experimental results. The proposed model might be beneficial to a transient analysis of a MAGLEV train coil system for its insulation coordination
