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, ...

www.quadtech.comOver the past 3-1/2 years, microprocessor current has increased by a factor of 5 and equivalent series resistance (ESR) has dropped by a factor of 7. Next-generation microprocessors ...

The Quick-Check Transformer & Capacitor Tester from HD Electric is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the ...

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 ...

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 ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance ...
