Product Description

PRODUCT INTRODUCTION:
        WT-XL passive filter compensation device consists of filter capacitor, filter reactor, thyristor switching device, controller and protection system. The filter compensation branch is designed according to the harmonic characteristics, content and reactive power of the system. Its working principle is to provide a channel with very low impedance for the harmonic current of a certain frequency, and form a shunt relationship with the grid impedance, so that the harmonic current of the frequency flows into the filter branch, so as to greatly reduce the harmonic current injected into PCC point and the harmonic voltage distortion rate of the system.
        The compensation device is especially suitable for various electric fields with large harmonic current and low power factor in metallurgical smelting, tire manufacturing, cement products, plastic packaging, steel rolling and copper rolling, coal mining and other industries.
