Active Harmonic Filter vs Passive Harmonic Filter Modern facilities depend on equipment that improves efficiency and control, but that same equipment often creates serious power quality problems. In an industrial power system, nonlinear loads such as variable frequency drive units, rectifiers, UPS systems, welders, and switched-mode power supplies can generate harmonic distortion. Once harm...
Capacitor bank overheating is a common problem in modern electrical systems. Many facilities install capacitor banks for power factor correction, but the capacitor bank still runs hot, trips, or fails early. In many cases, capacitor bank overheating is caused by harmonic distortion. Harmonic distortion puts extra electrical stress on the capacitor bank. A capacitor bank is designed to supply react...
