China 20Hz to 300Hz AC Resonant Test Set Frequency Power Systems for 20kv 600MW Hydroelectric Generator, Find details about China Resonant Test System, AC Resonant Test System from 20Hz to 300Hz AC Resonant Test Set Frequency Power Systems for 20kv 600MW Hydroelectric Generator
This device will be in resonant state by adjusting the inductance value of the inductor or the working frequency of the whole system or both methods. Adjust the frequency of the excitation transformer to the required frequency, then adjust the inductance of the inductor according the inductance value of the measured equipment, make the system in resonant, and generate high voltage, if the resonance point is deflected during the voltage boosting process, can regulate the frequency to correctly find the resonance point to ensure the high Q value, in order to farthest lessen the volume and weight of the measured equipment and power capacity.
