Overview:

SNA-AHF series active harmonic filter is a new type of power quality improvement production for dynamically filtering harmonics and compensating reactive power. It can filter and compensate harmonic (variable in orders and frequency) and dynamic reactive power in real time. It is used to overcome the shortcomings of conventional harmonic suppression and reactive power compensation methods such as passive harmonic filters, and achieve the harmonic filtering function and reactive power compensation function of the system.
