Abstract

A photographic investigation of the surface discharges on specimens of four polymeric materials is described. These materials are polystrene, polyvinyl chloride, teflon and prespex. Tests are performed under A. C. voltage on square specimens each of side length 10 cm and thickness of 0.5 mm to 6mm in non-uniform field consisting of wire and plane electrodes. The wire electrode has diameters ranged from 0.3 mm to 6 mm. The inception voltage of the surface discharges is found to be dependent on both factors namely the wire diameter and material thickness. The relationship between this voltage and either of the two factors is proposed to be in the form of a straight line formula. 
The surface discharges are recorded by a photographic camera using the four above-mentioned polymeric materials. The inception voltage is determined by means of an oscilloscope. Some selected close-up photographs are given here as example to demonstrate the nature of the surface discharges. The oscilloscope current traces of these discharges are also recorded by the camera and some of the reproduced photographs are also given for different wire diameters and material thickness.
