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 ...

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 ...

Used with a DMM on the 20V range, this circuit gives a rapid and direct measure of the leakage current of capacitors. There are two ranges, with maximum readings of about 20µA and 2mA, and the test ...

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

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 ...
