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

    ABSTRACT: A dynamic model to describe the nonlinear surge-current characteristics of several concentrated earths has been developed. The model accurately accounts for the surge behaviour of these earths on a time-to-time basis, in soils with resistivities ranging from 5000 ¿ cm to 31 000 ¿ cm. This results in a significant improvement over the previous methods used to describe them. The use of the new model for studies of concentrated earths at high lightning currents reveals that greater surge reduction factors than was previously assumed can be expected. This study serves to overcome previous difficulties in having to extrapolate values from meagre experimental results.

    ABSTRACT: An analytical model for the shielding of transmission lines against lightning is extended to the case of partially effective shielding, including the effect of possible leader approach angle distributions. Results of the Pathfinder projects are brought up to date, and the data are shown to be consistent with the model. An index number is developed to aid in classifying line performance, and suggestions are made regarding the study of the backflash problem.

    ABSTRACT: A method has been developed to predict the probability of a double circuit outage on double circuit lines. Traveling wave techniques are used to account for nonlinearities such as corona, attenuation, and phase conductor flashover as its time iterative approach enables alteration of design parameters at each time increment. A geometrical model technique, involving comparison of lightning voltages measured on the models with those obtained from linear traveling wave calculations, enables realistic estimation of the value ascribed to tower surge impedance, an important parameter in the calculations.
