Abstract :
This work presents the results of three stages of research performed on energy-efficient electronic ballasts for T8 fluorescent lamps: (a) laboratory experiments on 1φ and 3φ configurations, (b) field testing on a building before and after retrofit, and (c) computer simulations of a building, and of an actual 12 kV feeder with residential, commercial, and industrial loads. Some of the results indicate: (1) VTHD (total harmonic distortion) reduction when magnetic and electronic ballasts are combined, (2) neutral current increase or decrease in 3φ electronic-ballasts configurations depending upon its type, and (3) decrease in VTHD along the modeled feeder for lightand heavy-loads after retrofit, and a “maximum allowable” ITHD for an electronic ballast for retrofit
