Active harmonic filter and voltage stabilizer improving power quality and reliability in lighting, HVAC, and elevator systems
Commercial complexes are heavily loaded with nonlinear electrical equipment, including LED and fluorescent lighting systems, elevator drives, central HVAC units, and data center servers. These devices generate significant harmonic distortion, leading to transformer overheating, capacitor resonance, accelerated cable insulation aging, system malfunctions, elevator stoppages, display flickering, and energy loss.
Moreover, such facilities demand high voltage stability. Fluctuating voltage can cause elevator operation failures, HVAC cooling or heating disruptions, and unstable lighting brightness, all of which directly affect building operations and occupant comfort.
In a commercial building with a 2000 kVA transformer (10/0.4 kV) and a maximum system current of 1200 A, current distortion levels reached 20–35%. Installing the Active Power Filter reduced harmonic distortion, minimized transformer and cable heating, lowered equipment failure rates, and significantly enhanced the reliability and power quality of the entire electrical distribution system.

Our SBW-1200 kVA voltage stabilizer employs a dynamic compensation mechanism to maintain a stable output voltage within the required range of sensitive systems. For elevators, it prevents frequent start-stop cycles caused by voltage fluctuations, reducing mechanical wear. Built-in overvoltage and undervoltage protection safeguards against electrical hazards such as overheating or fire, ensuring safe and stable building operation.
