Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...
Washing machines perform several rinses after the main wash to remove most of the detergent. Modern washing machines use less hot water due to environmental concerns; however, this has led to the problem of poor rinsing on many washing machines on the market, [125] which can be a problem to people who are sensitive to detergents.
Generally, static VAR compensation is not done at line voltage; a bank of transformers steps the transmission voltage (for example, 230 kV) down to a much lower level (for example, 9.0 kV). [5] This reduces the size and number of components needed in the SVC, although the conductors must be very large to handle the high currents associated with ...
Some types of industrial sensors use a capacitor element to convert physical quantities such as pressure, displacement or relative humidity to an electrical signal for measurement purposes. Capacitive sensors can also be used in the place of switches, e.g. in computer keyboards or "touch buttons" for elevators that have no user-movable parts.
Capacitance sensors (or Dielectric sensors) use capacitance to measure the dielectric permittivity of a surrounding medium. The configuration is like the neutron probe where an access tube made of PVC is installed in the soil ; probes can also be modular (comb-like) and connected to a logger.
An LCR meter can also be used to measure the inductance variation with respect to the rotor position in permanent magnet machines. (However, care must be taken, as some LCR meters will be damaged by the generated EMF produced by turning the rotor of a permanent-magnet motor; in particular those intended for electronic component measurements.)
