Power Factor Correction Capacitors: Part 2

We covered some of the reasons for installing power-factor capacitors, along with some of the harmonics issues that can arise in such projects, in the first installment of this two-part article. Here we cover strategies for identifying and addressing potential problems. Engineers need to consider an electrical system's harmonic content when using power-factor correction capacitors. These devices won't produce harmonics, but they can magnify existing harmonics under certain conditions.
