What is the purpose of a capacitance meter?

A capacitance meter is specifically designed to measure the capacitance of capacitors. This measurement is crucial in electrical work, as it helps determine whether a capacitor is functioning correctly or if it needs to be replaced. Capacitors play a vital role in various electronic circuits, and understanding their capacitance allows a lineman to ensure that the components are operating as intended.

When the capacitance value is measured and compared to the specified rating of the capacitor, technicians can identify if there are any issues such as degraded performance due to age, temperature effects, or physical damage. By doing so, they can maintain the reliability and efficiency of the electrical systems they work on.

In contrast to the other options, which focus on measuring inductance, testing for resistance, or assessing voltage levels, the capacitance meter's unique purpose is centered squarely on capacitance—which is why it is essential for diagnosing and maintaining capacitors in electrical circuits.
