Contactor Switched Automatic Harmonic Filter Panel

Contactor Switched Automatic Harmonic Power Factor Correction (AHPFC) Panel is centralized reactive power compensation with harmonic mitigation. Automatic control is provided using automatic power factor control relays. The switching of individual steps is through contractors based on the load variation pattern, the minimum and maximum size of steps can be determined to maintain optimum power factor. This will help partly to mitigate the harmonics of the system.
