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 ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

The transformer and capacitor tester, developed by Hastings, a global supplier of hot line tools and equipment, ensures the safety of hotline workers so that they can perform their jobs with ...

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, ...

In this video, I demonstrate how to test and install an AC capacitor, providing insights to help save money and prevent ...

Normally, a typical multimeter is designed to measure parameters such as voltage, current and resistance over a wide range of values. This analog capacitance meter has 5 switched range values of 1nF, ...
