Certified solutions to control harmonics Advanced active filters Advanced harmonic filters Low harmonic drives 12-pulse drives Active front end drives Adverse effects of harmonics Limitations on supply and network utilization Increased transformer, motor and cable heating Reduced equipment lifetime Costly equipment downtime Control system malfunctions Pulsating and reduced motor torque Audible noise Harmonic mitigation While AC drives increase precision, save energy and extend application lifetime, they also introduce harmonic currents to the on-board grid. If not kept under control, this can affect the performance and reliability of generators and other equipment and, ultimately, compromise safety. Danfoss offers harmonic mitigation solutions to comply with the regulations. Danfoss has developed a wide range of mitigation solutions which can help restore weak networks, increase network capacity, and meet compact retrofit demands – or secure sensitive environments. Low harmonic drives The VLT® low harmonic drives continuously regulate the network and load conditions without affecting the connected motor. The drives combine the well-known performance and reliability of standard VLT® drives with an Advanced Active Filter. The result is a powerful, motor-friendly solution that provides the highest possible harmonic mitigation with total harmonic current distortion (THDi) of maximum 5%.
