Real-time reactive power compensation with the help of Merus™ Active Harmonic Filters

Better weld quality by reducing flicker and load unbalance with

Reactive power demand was fluctuating rapidly during a 120ms welding cycle in a Russian industrial plant. Conventional capacitor banks were too slow to respond to fast fluctuating reactive power demands. The resulting flicker was experienced even by other customers connected to the same busbar.

An onsite power quality audit confirmed load unbalance. Merus™ Active Harmonic Filters were installed parallel to the disturbing loads and configured to fundamental dynamic reactive power compensation and load balancing functionality. Post-installation testing has confirmed flicker mitigation, load balancing and improved welding quality.
