Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Virtually every type of electronic hardware incorporates capacitors, which are widely used for functions such as bypassing, coupling, filtering, and tunneling electronic circuits. However, to be ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

When checking and verifying capacitors, inductors, diodes, bipolar transistors, and cables, the gamut of test methods can range from those used to confirm a defective component to identifying the ...

The loop output can go directly to an ADC (analog-to-digital converter) or DMM in the configuration of K22 shown. If, however, filtering is needed to reduce noise during measurements, K22 can be ...

Designers have long used the gyrator circuit to create a virtual inductor employing readily available capacitors. The circuit can achieve high inductance values with relatively low capacitance values, ...
