Generator AC Withstand Voltage Resonant Device



Generator AC Withstand Voltage Resonant Device achieves resonance by adjusting the inductance of the reactor, or by adjusting the system operating frequency, or by both methods simultaneously. When a test requires a specific frequency, adjust the excitation source frequency to the desired value, then adjust the reactor's reactance according to the capacitance of the test object to achieve resonance and generate high voltage. During the voltage increase process, if the resonance point deviates, it can be accurately found by fine-tuning the frequency, ensuring a high Q value, thereby reducing the power supply capacity and the volume and weight of the test equipment.
