Analyzing electric power quality in arc furnaces

Abstract

The paper presents the analysis of the results carried out at Lloyds Steel Industries, Wardha, Maharashtra State, India. The various electrical quantities like voltages, currents, frequency, and flicker etc. regarding power quality are measured and recorded at different voltage buses; the same are compared with power quality standards. The AC Electric arc furnaces generate harmonics. Power quality disturbances such as harmonics, snapshots, and transients are investigated and found to be high.
