Evaluating tuned capacitor banks for South America

This paper will review history of applications of tuned capacitor banks applied in mills. North American users are familiar with tuned capacitor banks operating at 480 V or 600 V and on a 60 Hz system. Selecting the right tuned capacitor bank could be a challenge if faced with a different power system such as 400 V and 50 Hz. The calculation of the actual capacitor kVAr at the applied voltage and frequency will be shown. The sizing of the tuning reactor and the voltage rise on the capacitor calculations will be provided. In addition, the heat gain of the capacitor bank will be addressed. Many successful global companies endeavor to use standard components to achieve the desired power factor correcting performance while maintaining competitiveness. An end user needs strong technical knowledge to perform the analysis to differentiate the variety of proposals to select the most suitable option
