AC Test Transformer
-
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.
