A low cost approach to design the tesla transformer for testing of insulating materials and industrial applications

Abstract

In view of the stringent quality requirements for solid dielectric bushing, a wide range of quality assurance techniques is applied. High frequency testing is by far the most effective destructive test for screening and rejecting poor quality insulation bushing. This paper presents the design and construction of a tesla transformer for defective insulation testing. The attempts of developing a prototype have low cost of all components. A design technique and testing method will be fully given. The calculation is based on the stress control so that the optimum electric stress can be obtained. A high frequency generator has been tested and used in bushing factory for routine tested according to TIS. 354-2523 (Thai Industrial Standard). From the results, the prototype unit has accuracy with in acceptable level.
