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...
SVG for Industrial Motor Loads Motor loads are common in factories, mines, water treatment plants, commercial buildings, and pumping systems. These loads are reliable and useful, but they also create reactive power demand. When reactive power is not controlled, the system may face poor power factor, higher current, voltage instability, and extra stress on electrical equipment. This is why S...
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...
How Regenerative Loads Affect Industrial Power Quality Regenerative loads are common in modern industrial systems. They appear when a motor changes from consuming power to returning power. This often happens during braking, lowering, deceleration, or rapid speed changes. Cranes, hoists, elevators, rolling mills, centrifuges, test benches, and conveyor systems can all create regenerative loads. The...
