Abstract
With the rapidly increasing number of electronic ballast manufacturers and ballast products entering the market recently, the compatibility of fluorescent lamps with electronic ballasts has become one of the ma jor concerns among specifiers and users In 1993, the American National Standards Institute (ANSI) published ANSI C82.11-1993, which describe s recommendations for high frequency operation of fluorescent lamp bal lasts, to address compatibility issues for lamp starting, ANSI C82.11 limits the average value of the rms glow current to a maximum of 25 mA and lamp preheat time to a minimum of 500 ms. Tbe ANSI's definitions of flow current and preheat time are made on an ideal lamp starting cu r, e. In reality, some electronic ballasts produce lamp starting curl es very different from ANSI's definition, creating difficulties in pra ctical measurements of glow current and preheat time. This research wo rk tested lamp starting characteristics of 17 different electronic bal lasts on 2-F40T12 lamps The results showed that the starting performan ce of electronic ballasts varied; some met ANSI's requirements, but so me did not, ?he results also showed that using electrode voltage can b etter define preheat time and glow current, which can better character ize the starting performance of electronic ballasts and ensure reliabl e testing procedures.
