THE PIONEERING WORK BY ZELLER ON TREEING IN INSULATING MATERIALS: SOME COMMENTS

George E. Vardakis - Michael G. Danikas

   In this paper, comments are offered on the pioneering work of H.R.Zeller about the initiation and propagation of electrical treeing in solid insulating materials. The basic aspects of Zeller's research are mentioned. His major contribution, ie the development of the notion of the field limiting space charge (FLSC) is approached critically and the role of recombination of positive and negative charges - not considered by Zeller - is discussed.

Keywords: treeing, inception, FLSC, fractal model, local field
