Comments on: "A Critical Review of Partial-Discharge Models" (Nov/Dec 2012), &anp; "Analysis of the Partial Discharge Charge Transfer in Extruded Power Cables" (Jan/Feb 2013) [Letter to the editors]

In a technical paper, the words serve to introduce the concepts in order to make the equations more easily understood; however, the real technical content, for which the author should be held accountable, is in the equations and, perhaps, the conclusions. If you take this perspective on Prof. Lemke's two recent papers on partial discharge models, the equations are reasonable approximations for the more exact field-based theory of Pedersen. In that context, I believe that Prof. Lemke's papers are "correct," and I have conducted numerical simulations to check that belief. From my perspective, the controversy surrounding these papers is the result of imprecise language in the text, but the equations make the point, as do the conclusions.
