Abstract

This paper presents results of field measurements of power quality indices at the terminals of an Electric Arc furnace connected at 34.5 kV to a 230 kV 60 Hz network in Saudi Arabia. The power quality indices that are measured are total harmonic distortion for voltage and current (THD V, THD I), individual harmonics, and flicker for short and long terms (P_st, P_lt). In addition, other electrical parameters are measured as well such as voltage (V_rms), current (I_rms), active power (P), reactive power (Q), power factor (PF), and frequency. All power quality parameters for both study cases are found to be within the IEEE and IEC standards. The installation of SVC and filters are mandatory. Long term Monitoring and country wide PQ study is recommended.
