Applying Type DD60 Capacitors in Harmonic Filter Applications

Applying Type DD60 Capacitors in Harmonic Filter Applications This application note provides guidance for the proper selection and applying type DD60 capacitors in harmonic filter application. Harmonic filters present more strenuous applications for a capacitor than a typical power factor system. Special care must be taken to properly specify voltage, current and ambient temperature requirements. [...]

Advancements in AC Power Capacitor Manufacturing

Advancements in AC Power Capacitor Manufacturing Capacitors used for power factor or harmonic filter applications have traditionally experienced some problems when transient over-voltages or over-current caused case ruptures, especially when capacitor failures involved oil leaking out. Problems such as these have caused reluctance by some engineers to specify power quality filters involving capacitors. FRAKO has [...]

Causes of Premature Failure of Power Factor Capacitors

Causes of Premature Failure of Power Factor Capacitors This article explains the various causes of premature failure of power factor capacitors and presents some best practices to extend the useful life of AC Power Factor Capacitors. In order to understand capacitor failures, it is helpful to first understand a bit about capacitor construction. 3-phase Capacitor [...]
