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 ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

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 ...

In the 1930s and up to and after World War II, several companies manufactured vacuum tube analyzers specifically for testing capacitors (then called condensers). Although many of today’s digital ...

Ever wonder what goes on inside of an electrolytic capacitor? Nick Visic from AiSHi Capacitors shows how these popular capacitors work in this tear-down video from DesignCon. The screw terminal ...
