Design and Implementation of a 125 kV/1000 kVA High-Voltage Test System Using Scrics-Resonance Technique

This paper presents the design, analysis, simulation, and implementation of a high-power resonance generator for testing high-voltage capacitivc loads. The resonance generator includes a variable reactor which is (he most important part of (he system, a shielded isolation transformer, a voltage regulator (auto-transformer), an exciter transformer, a capacitive divider, a control cubicle, a digital voltmeter, a computer hased partial discharge measurement system, a high-vollage filter, and a low-voltage 11 Iter. 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 indnctanee measurement of the implemented variable reactor matches with the simulation results. The partial discharge measurement of the implemented high-vollage series-resonance test system shows that the system is PD free up to 70 kV.
