Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

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 ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

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 ...

When a crew employed by a local electric utility set out to conduct a DC hi-pot test on a new circuit breaker, the task seemed like nothing more than a routine call. Unfortunately, the events that ...

Overload prevention in any given design is serious business, which means that the choice of safety capacitor shouldn’t be taken lightly either. Areas to consider in the decision process include safety ...

High-voltage Multi-Layer Ceramic Capacitors (MLCCs) are great for roles such as coupling, DC blocking, snubbing, or power-supply resonators. Their high volumetric efficiency delivers high capacitance ...

Power Integrations' CAPZero automatic X-capacitor discharge IC is now certified to meet IEC CTL DSH 1080, the new mandatory addition to the Certification Body (CB) scheme of the IEC60950 and IEC60065 ...
