Abstract
Impulse voltages are required in highvoltage tests to simulate the stresses due to external and internal overvoltages. Thereby, care should be taken to the effect of the different loading conditions on the impulse generator, since changing the load nature will change the response of the impulse generator and may lead to undesired waveforms. This thesis introduces a modified algorithm for the solution of the generalized equivalent circuit for impulse generator under any loading condition. Evaluating partial fraction expansion by means of the very common used MATLAB<U+2122> package enables the solution of the complex voltage waveform of the generalized circuit in a rapidly converging manner. The algorithm is not only capable to evaluate the voltage waveform resulting due to the coupling of any load nature to an impulse generator for given parameters, but also to predetermine the impulse generator parameters needed for producing a given voltage waveform, when coupling the generator with any kind of load. The high efficiency of this algorithm has been verified through experimental investigations and checked by PSCAD(R*?(BEMTDC<U+2122> simulation on different capacitive, inductive as well as transformer loadings. Closely agreement is found between the numerical and experimental results.
