The arrester is usually connected between the live wire and the ground, and is connected in parallel with the protected equipment. When the overvoltage value reaches the specified operating voltage, the arrester will act immediately, flow the charge, limit the overvoltage amplitude, and protect the insulation of the equipment; when the voltage value is normal, the arrester will quickly return to its original state to ensure the normal power supply of the system.

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.

The short-circuit test system refers to what kind of short-circuit test is carried out by which equipment, and how long is the test time. But I have one thing to tell you, the short circuit test is a kind of destructive test, mainly to test the working condition of the used equipment in a crisis situation, or to test how strong the anti-destructive ability of the used equipment is. Just like a lot of equipment in the military must undergo a short-circuit test, some for 3 minutes or longer, in order to resist breaking calls against the enemy during wartime.
