High Voltage Passive Filtering Device
The WT-TAL filter device is based on the principle of capacitive reactance resonance. After fine tuning the LC, the filter can present a low impedance to the high-order harmonic current of a certain frequency, and redistribute the harmonics flowing into the system and the filter. At the same time, it can also transmit capacitive reactive power to the system to adjust network voltage, reduce line loss, and improve the efficiency of power supply and distribution equipment. Improve system power quality.
