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 ...
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, ...
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, ...
