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 ...

We all know that capacitors are necessary to the proper functioning of any HVAC system. Yet, some in the HVAC industry have elected to make capacitor selection decisions based primarily on price.

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 ...

Back in 2006 I wrote about how my friend Alan Martin over at Texas Instruments had a saying: “It’s always a capacitor.” This was based on his observance that there is a lot of test equipment that goes ...
