What is the difference between the filter compensation module and the smart capacitor?

Smart capacitors are divided into two types. One is a smart capacitor that includes a filter module. We call it an anti-harmonic smart capacitor, and the other is a capacitor that has only a capacitor and a control module. We call it an ordinary smart capacitor. .

So where exactly is the difference between the two? The anti-harmonic type smart capacitor is composed of a filter, a reactor, a capacitor, and a control module. The reactor is equipped with a filter function, which can effectively suppress the effects of higher harmonics and inrush currents by forming a low-impedance path to higher harmonics. At the same time, the filter module absorbs and discharges harmonics, and can eliminate high-order harmonics. And the impact of electrical equipment, place the protection circuit and capacitor overload, to prevent the capacitor temperature is too high, the insulation medium aging, self-healing decline, reduced service life and so on.

The reactance rate of the filter module is 6%, 7%, 13%, 14% and several specifications. They are used for power consumption occasions with different levels of harmonic content. The use of anti-harmonic smart capacitors in power distribution equipment can effectively filter out the circuit. The harmonics and interferences in the system ensure the stability of the electricity environment for each electrical equipment, and effectively increase the power factor. In short, the anti-harmonic smart capacitors are used in complicated electrical environments, harsh environments, and in high-volume and different equipment power environments. Power factor is an indispensable helper to improve equipment operation life and save power resources.

Because of the lack of filter compensation module, ordinary smart capacitors naturally do not have the filtering function, so they are not suitable for reactive power compensation in large harmonics and complex electrical environments.
