Tuned capacitor bank component selection – what difference does it make?

Paper plants without generation often have power factor and harmonic current issues to solve, and they have to be solved for the plant to operate. The easiest solution is typically a tuned capacitor bank, but someone has to design the bank. The design of a tuned bank involves selecting total VARs, the number of capacitor cans per phase, the voltage rating of the cans, and the bank tuning frequency. The purpose of this paper is to explore differences in bank performance that result from these selections. Four banks built with different components, all producing about 3 MVAR, are examined in this paper.
