The results of this paper suggest that surge arrester protection may not be adequate for very fast rates of rise of lightning currents even considering insulation strength greater than chopped-wave. Additionally, it is shown that prediction of the ma

The theoretical transient solution of multiphase transmission line propagation is reviewed by comparison of the Fourier and Laplace transform techniques applicable to this problem. The results show that the Fourier transform technique is more general

The implementation of a new three phase travelling wave program is discussed. The unique feature of this program is the use of Thevenin equivalent circuit for representation of line terminal conditions. This allows the use of linear or non-linear dif

In considering the use of insulated and transposed ground wires for communications or other purposes, the magnitude of the ground wire losses were determined so that the losses could be properly evaluated as a cost or credit for this use when compare
