AI Customer ServiceIntroduction Capacitors, as energy storage components, are widely used in various circuits. In order to ensure the normal operation of the circuit, it is sometimes
AI Customer ServiceTo test a capacitor, select the capacitor setting on the multi-meter. This is normally under resistance and is often displayed as nF as the unit on the screen. Hold the test leads on 'A' and 'B'. Hold the test leads on the terminals of the capacitor, 'A' and 'B', for testing. It normally takes a few seconds to get an accurate reading. Compare the reading you get from the multi-meter to what is specified on the casing of the capacitor.
To test a fixed safety capacitor below 10pF, you can only qualitatively check for leakage, internal short circuit, or breakdown using a multimeter. When measuring, use a multimeter's R × 10k block and connect the two pins of the capacitor with the test leads. The resistance should read infinitely high.
To test a film capacitor: First, check its appearance. If there's a problem, the capacitor may have issues. Next, test the two legs with a multimeter. The resistance should be very high. If you have a capacitance meter, measure the capacitance value and compare it to the mark on the housing.
When a new design of power capacitor is launched by a manufacturer, it to be tested whether the new batch of capacitor comply the standard or not. Design tests or type tests are not performed on individual capacitor rather they are performed on some randomly selected capacitors to ensure compliance of the standard.
This test is performed on each capacitor unit to demonstrate, the loss occurs in the unit during operation is less than the maximum allowable loss of the unit. In this test the capacitor unit is first charged with direct voltage (DC) up to 1.7 times of the rated rms voltage of the capacitor unit.
You don't check. To choose the capacitor, you go to the manufacturer data sheets of the capacitors, which will have the specifications you need to help you choose. You buy from a reputable distributor, and specify the capacitor you want. That way, counterfeits and substitutions are less likely.
