Another way to measure the quality of high voltage capacitors

As for the method of high-voltage capacitance measurement, I believe that everyone knows a lot. Then, if there is no measuring instrument, there is another way to judge whether the high-voltage capacitor is good or bad. This article gives you another method for this problem. I hope this article is for everyone. helpful!

You can use a voltage regulator, a current meter and a voltmeter (which can be replaced by a multimeter) to add an integer current to the capacitor (controlled by a voltage regulator), then calculate the capacitance impedance based on the voltage and current readings, and then divide the calculation by 3184. The capacitance value, the result is almost the same as the capacitor superscript, but the high voltage capacitor is broken. In addition, the capacitor is tested for withstand voltage. The two plates are sealed with a wire and subjected to a ground pressure test. If there is no high voltage generator, it can be grounded to the ground with a 2500V shaker.

If there is no voltage regulator, you can also use the 2500V shaker to shake the phase. During the process of shaking, the resistance value will gradually increase. However, if the watch is stopped, the needle should be reversed immediately. Otherwise, the high voltage capacitor has a problem. Remember to discharge after shaking. In the use of some related precautions, we must also pay attention to it, the standard use, there will be protection.
