Abstract

This paper presents the design and construction of a high voltage and high frequency switching source for defective insulation testing. The attempt of developing a prototype has been made in order to replace a conventional tesla transformer method based on L-C resonance which has some limitations such as large size, heavy weight, damping signal, unstable voltage and control difficulties. With the inherent characteristics of high frequency source, defective insulator surface can be easily detected. A design technique and testing method will be fully given. A prototype has been tested and used in a student laboratory for studying insulating material characteristics
