Static Var Generator SVG for Power Factor Correction A fabrication plant in Monterrey replaced its capacitor bank contactors every quarter. The 800 kvar bank tripped on overcurrent whenever five spot welding machines fired within the same second, and the utility meter recorded a lagging power factor of 0.78 — the plant paid a penalty surcharge on every invoice. The capacitors were not...
Medium Voltage Harmonic Filters: A Complete Selection Guide Medium voltage harmonic filters help industrial facilities, renewable energy plants, utilities, and infrastructure projects control harmonic distortion in their electrical systems. Harmonics can reduce power quality, increase equipment losses, create overheating, and interfere with normal system operation. A correctly designed harmonic fi...
Stop Hidden Power Costs from Automotive Dynamic Loads: Benefits of Power Quality System Upgrade Automotive assembly lines operate with extreme load volatility. High-power lifting equipment and robotic welders demand instantaneous reactive power during startup cycles. Traditional capacitor-based compensation systems fail to track these millisecond-level transients, leading to severe power factor pe...
SVG for Reactive Power Compensation in Industrial Plants A shovel line that punished the capacitor bank A copper mine in Chile ran an 800 kW electric shovel with 1.2 MW peaks on a 690 V bus. Voltage flicker (Pst) measured 1.6 against the 1.0 limit, and the cont...
