Case Study

In tire manufacturing plants, production equipment such as internal mixers, vulcanizers, and forming machines typically use variable-frequency drives or DC motors, which are classified as nonlinear loads. During operation, these systems generate a large amount of harmonic current that flows back into the grid, causing voltage waveform distortion, equipment overheating, and relay protection malfunctions, all of which threaten production stability.

To address these issues, a tire manufacturing facility adopted our Active Harmonic Filter (AHF). By continuously monitoring harmonic components and injecting counter-phase compensation currents in real time, the system effectively eliminated harmonic pollution in the power network and ensured the safe and stable operation of all production equipment.
