Experimental Research on the Voltage Distribution of Tesla Transformer's Taper Windings

Summary form only given. By using the taper high voltage windings, the Tesla transformer with compact structure can be built. However, the flashover between coils will occur because of un-uniform of the voltage distribution along the windings. Therefore, researching the voltage distribution of the Tesla transformer, improving the distribution by appropriate method and designing optimized structure of the windings would highly improve repetitive ability of the transformer, which have theoretical and engineering significance for the Tesla transformer's working in reliable and security. In order to study the voltage distribution on the pulse transformer's taper windings, according to the structure of the factual pulse transformers taper windings, the voltage of a uniform tesla transformer's windings was measured in the paper. It is shown that the voltage distribution of taper winding is not uniform, and the distributed curve of its interturn voltage is U shape with 100ns pulse. Based on the results, the methods to improve the distribution of the tape winding were bring forwards by measuring and analyzing the voltage distribution of other taper windings with different structure. These results can give some references to interturn insulation designs of Tesla transformer's windings.
