Measuring Capacitors

The known capacitor is referred to as the ''standard'' capacitor and is often a high-accuracy type meant for testing, hence the ''s'' designator. However, the simple capacitance bridge circuits commonly found online and in educational texts suffer from a major problem: They really only work with near-perfect capacitors, which means air-gap, quality mica capacitors, or some film

Helpful Tips on Measuring Capacitors

Measuring a capacitor in series or parallel mode can provide different results. How the results differ can depend on the quality of the device, but the thing to keep in mind is that the capacitor''s measured value most closely represents its effective value when the more suitable equivalent circuit, series or parallel, is used.

Measuring a Capacitor

The key to measure the capacitance and dissipation factor correctly is the meter settings. The voltage settings are critical for high capacitance capacitors. For some cap meters, the applied voltage to the test component is not enough and the capacitance reads low. The frequency settings are also important. Since capacitance changes with

Power Quality: Definition, Why and How Do We Measure It?

6 FAQs about [Standards for measuring the quality of capacitors]

How difficult is it to calibrate capacitors for use as standards?

Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.

How to measure capacitance & dissipation factor correctly?

Which meter setting should I use to measure capacitance?

Therefore, Cs should be used for the meter setting to measure capacitance. A good rule of thumb to select the impedance setting is to use Cp for capacitor impedance values greater than 10kΩ and Cs for less than 10Ω. How can I accurately measure the quality factor (Q)?

How do you measure the quality of a capacitor?

Often multiple coils are necessary to adequately measure across the 0.5 ～ 330pF range. For capacitors > 330pF, the quality factor can be calculated by taking the inverse of the dissipation factor (see Formula 1). What is the allowable ripple current of capacitors?

What is the quality factor of a capacitor?

The quality factor is a measure of the extent to which a capacitor acts like a theoretically pure capacitor. It is the inverse of the dissipation factor (DF). Q is typically reported for capacitance values ≦ 330pF, DF > 330pF.

How do I choose a capacitor?

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.
