The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



an instrument for measuring the capacitance of electrical equipment—such as capacitors and cables—that runs on commercial-frequency alternating current. In direct-acting faradmeters, the measuring mechanism is an electromagnetic, electrodynamic, or ferrodynamic quotient meter; the scales of such faradmeters are marked in microfarads and picofarads. Rectifier faradmeters have an electromagnetic measuring mechanism.

The readings of a faradmeter depend on the voltage supplied to the instrument. For this reason, a faradmeter must be adjusted, by moving the pointer of the instrument to the zero point of the scale, before a measurement is made. The measurement error is 1–4 percent.
