What is an active filter? What does it do?
What is an active filter and what is its function? Active power filter is a new type of power electronic installation used to dynamically suppress harmonics and compensate reactive power. It can stop fast tracking compensation for harmonics of different sizes and frequencies. The reason why it is called active is related to passive LC filter. APF can only passively absorb harmonics of fixed frequency and size. APF can sample load current and stop the separation of harmonics and reactive power, control and active output current size, frequency and phase, and fast response, offset the corresponding current in the load, complete the dynamic tracking compensation, and can complement both harmonic and reactive and unbalanced.

What are the differences between SVC and SVG in dynamic reactive power compensation
Talking about the differences between SVC and SVG in dynamic reactive power compensation: let's first talk about what SVC is. In fact, the full name of SVC should be called dynamic reactive power compensator, which can be regarded as a dynamic reactive power source. According to the needs of access to the grid, it can provide reactive power to the grid (capacitive), but also to absorb the excess reactive power grid (rational). It has a capacitor that releases reactive power and a reactor that absorbs excess non-capacitive reactive power, so it is a dynamic compensation of reactive power.

Active filter how to sure product selection?
Active filter how to affirm product selection? ① understand the installation capacity of active filter installation capacity is by the management of harmonic current output can be expressed, the unit is ampere (A). The larger the installed capacity of active filter, the higher the total price. For example, a 300A active filter of the same brand is more expensive than a 100A active filter.

Hasecke shows you what reactive power compensation is.
Hesreko will show you what reactive power compensation is: reactive power compensation is a technology that plays a role in improving the power factor of the power grid in the power supply system, reduces the loss of power supply transformers and transmission lines, improves power supply efficiency and improves the power supply environment. To understand reactive power compensation, we must first understand several concepts, "active power" and "reactive power" and "power factor"
