How to measure the quality of high voltage capacitors
Everyone knows that the voltages of high voltage capacitors are 1KV, 2KV, 3KV, etc. Recently, I have seen a small partner suggest how to judge the quality of their 10KV high-voltage capacitors. In fact, the method is very simple. I hope it can also help novices to solve such problems.

To judge the quality of high-voltage capacitors, it is mainly to judge whether there is internal breakdown! It can be measured with a shaking table (note that after the measurement, use a wire to discharge between the two poles, otherwise you will suffer an electric shock). There are two other test methods as follows:

1. Use a multimeter to directly test the resistance at both ends. If you are using a pointer multimeter, like most capacitors, you can see the pointer swinging from small to large. See if the resistance returns to infinity.

2. It is connected to 220v AC mains in series to see if the bulb can be lighted normally. Determine whether the capacitor still has capacity. Whether the preliminary test is normal.How to measure the quality of high voltage capacitors
