Evaluation of the Integration Method for Analysis of Nonstandard Surge Voltages [includes discussion]

In evaluating surge protection applications it is necessary to consider surge voltages of many shapes, and evaluate their effect on the insulation of electric equipment. Since insulation performance is normally expressed in terms of certain standard waves, the desired method should give a means of comparison between wave shapes. The integration method, originally presented by Witzke and Bliss,1,2 provides such a means. The purpose of this paper is to present laboratory data to evaluate the accuracy of the integration method. It is concluded that the method provides a satisfactory technique for applying surge protection on a scientific basis.
