Test method for AC capacitors(II)

3. Incandescent bulb and capacitor series detection method

    If the incandescent bulb and the capacitor are connected in series to a 220V AC power supply, the capacitor is good if the incandescent bulb is darker than if it is directly connected to the 220V AC power supply; if the incandescent bulb is not lit, Indicates that the inside of the capacitor to be tested has been broken; if the brightness of the incandescent bulb is the same as the brightness of the incandescent bulb directly connected to the 220V AC power supply, the inside of the capacitor has been short-circuited.

4. Metrometer detection method

    It can also be detected by the mega meter (250 V). To shake a handle, such as a pointer at infinity, indicating an internal break in the capacitor, or a short circuit inside the capacitor, if the pointer is at zero. It is also possible to test the capacitors by connecting the metrometer connecting posts to the terminals and housing of the capacitors respectively. To shake a handle, such as a pointer at a zero, to indicate that the capacitor is inside the ground.
