Abstract: 

This paper presents the design, analysis, simulation, and implementation of a high-power resonance generator for testing high-voltage capacitive loads.
The resonance generator includes a variable reactor which is the most important part of the system, a shielded isolation transformer, a voltage regulator (auto-transformer), an exciter transformer, a capacitive divider, a control cubicle, a digital voltmeter, a computer based partial discharge measurement system, a high-voltage filter, and a low-voltage filter. The paper describes the analysis and simulation of different parts of the system. It also presents the results of tests were performed using the implemented system on different capacitive loads, including the measurements of harmonic distortions and partial discharge. The inductance measurement of the implemented variable reactor matches with the simulation results. The partial discharge measurement of the implemented high-voltage series-resonance test system shows that the system is PD free up to 70 kV.
