LUCCHINI SOUTH AFRICA (PTY) LTD is situated in Germiston. Lucchini manufactures high-quality forged railway wheels with a proven track record across Africa. These include locomotive wheels, freight wagon wheels and passenger railway wheels. Powerqube and partners supplied, installed and commissioned a 200A Active Harmonic Filter and 300kVAr Sinexcel SVG system at the Main Substation of the Lucchini Plant. The plant is equipped with large inductive loads and drives which creates a very poor power factor, current unbalance as well as high current and voltage harmonics with a fast fluctuating load. The Sinexcel SVG/AHF Hybrid solution ensure a stable voltage during Generator power, the system improved the current unbalance, correct the power factor to the required setpoint and reduced the current and voltage harmonics to be within the required specifications. These fast fluctuating loads together with the presence of current and voltage harmonics on the LV power networks resulted in the existing conventional switched-capacitor PFC System to fail and made it unusable. The existing PFC system was de-commissioned and replaced with the Sinexcel SVG/AHF solution.
