About this document
Harmonic Emission in Ballast Systems by Abhishek Thakur is a document available to read on EtoBox.
This document summarizes a study that compares the harmonic emission of high pressure sodium (HPS) lamps connected to either electromagnetic or electronic ballasts. The study measured harmonics under full and reduced power levels for various HPS lamps. It found that electronic ballasts can smoothly dim lamp output and reduce harmonic distortion compared to electromagnetic ballasts. Combining different HPS lamps can also decrease current distortion. The study proposes methods to reduce harmonic content, such
