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, ...

The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...
