    Abstract

    This paper describes a transmission line lightning performance
    analysis program QCORTL which is able to predict single and
    multi-circuit flashover and outage types and rates of a quadruple
    circuit transmission line. It employs the Monte Carlo statistical
    technique to select lightning and system parameters and the dynamic
    travelling wave technique to calculate overvoltages on transmission line
    towers. The program has also incorporated nonlinear corona effects, the
    dynamic response of soil and the modelling of wooden-crossarms for
    arc-quenching in its calculations. The assessment of a Malaysian
    quadruple circuit dual voltage 275/132 kV transmission line using this
    program is demonstrated to illustrate the detailed nature of the
    analysis that is suitable for insulation design of transmission lines
