The essence of DC high-voltage generatorSimply put, it is a device that can convert 220V mains power into tens or even hundreds of kilovolts of DC high voltage. The core technology is high-frequency pulse width modulation (PWM), which maintains high stability of the output voltage through closed-loo
Many people think that a transformer ratio tester is just to measure the transformer ratio, and then put it away after use. Engineers who have truly used HZTTR80A know that the testing function of this instrument goes far beyond just one variable ratio value, covering almost the entire set of indica
Those who engage in electrical maintenance cannot avoid a common issue: before a cable is put into operation, it must undergo a voltage withstand test. However, for a high-voltage cable several kilometers long, with a capacitance of several hundredths of a microfarad, using traditional power frequen
Recently, a colleague asked me, "When buying a high-current booster, the salesperson quoted a bunch of parameters, such as rated current, measurement accuracy, waveform distortion... I don't know which one to focus on." This article will help you clarify the core logic of selection fro
I. Preparation and preliminary verification before testingBefore conducting the test, ensure that the harmonic detector has sufficient battery power and that the function settings are intact. Verify that the equipment calibration label is within its validity period. Record the basic information of t
