This paper presents the design and construction of voltage acceptability curves for fluorescent lighting systems. It is derived from mathematical representation of actual light output variations of fluorescent lamps (FLs) during voltage sags and a predefined malfunction criterion called the light standard. Light standard may be thought of a standard based(More)
The widespread use of compact fluorescent lighting in residential and commercial application is a significant source of power pollution. The ballast that controls the operation of this type of lamp is known to generate peak currents and introduce harmonics into the distribution systems. Currently, compact fluorescent lamps (CFLs) with dimming function have(More)
The main emphasis of this paper is on analyzing the harmonics generated from compact fluorescent lamps (CFLs). Laboratory tests on various CFLs were conducted to tap the load current behavior under different conditions. Then frequency domain analysis is performed to investigate the generated harmonics from CFLs. Harmonic levels of dimmable and non dimmable(More)
