6 FAQs about [Measurement of capacitors in Antananarivo]

How a capacitor is measured?

One of these spikes is marked with an asterisk. With this measurement method the capacitor is inserted in a half bridge configuration which is connected to a sinewave generator. By the measured voltages and phase difference the capacity and ESR can be determined. Capacitors can almost be considered as ideal components.

How to measure the internal resistance of a capacitor?

To measure the internal resistance accurate the channel 2 probe must be placed as close as possible at the capacitor. The resistor Rs must have approximately the same value as the impedance of the capacitor. De first method describes the measurement of small capacitors whereof the series resistance is negligible. Fig. 5: Mathematical model.

Which method is suitable for measuring electrolytic capacitors?

The second method describes a measurement that is suitable for measuring on larger capacities and can also determine the internal series resistance (ESR). This method is thus mainly suitable for measuring on electrolytic capacitors. Figure 8 shows the mathematical model with the associated vector diagram in figure 9.

Can electrolytic capacitors be measured with a high ESR?

Only electrolytic capacitors who have a relative high capacity in combination with a high ESR, the measure frequency can kept low enough to be usable. When measuring other capacitors the frequency must be chosen lower than desired what means that only the capacitance can be measured.

Can a capacitor be measured if the frequency is lower than desired?

When measuring other capacitors the frequency must be chosen lower than desired what means that only the capacitance can be measured. Two examples are given: The first one is for measuring only the capacitance, and the second one is for measuring the capacity as well as the ESR.

What are parasitic properties of a capacitor?

A capacitor has beside the most important property; the capacitance, also parasitic properties. The most important of these are the series resistance and the self-inductance who is also connected in series with the capacitance. The model of a capacitor with its parasitic components is shown in the figure on the right.
