This work presents the results of three stages of research performed on energy-efficient electronic ballasts for T8 lamps: (a) laboratory experiments on 1{phi} and 3{phi} 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) V{sub THD} (total harmonic distortion) reduction when magnetic and electronic ballasts are combined, (2) neutral current increase or decrease in 3{phi} electronic-ballasts configurations depending upon its type, (3) decrease in V{sub THD} along the modeled feeder for light- and heavy-loads after retrofit, and a maximum allowable I{sub THD} for an electronic ballast for retrofit.
