Definition and measurement of roll-offRoll-off, as the name implies, is a measure of the attenuation rate of a high frequency filter near the cutoff frequency. ...
The 660V three-phase filter reactor is an electrical component specially designed to filter harmonics in power systems. It is mainly composed of coils, iron cor...
Low loss and high efficiencyA significant advantage of single-phase autotransformers is that they have low losses. This is due to their unique structural design...
As an inductive element, the core of three-phase AC input reactors lies in their inductive effect. When AC current passes through the reactor, a changing magnet...
Short-circuit fault is one of the most common fault types in power systems. When the insulation of electrical equipment is damaged or personnel misoperation cau...
Electrical faults occur from time to time in power systems, and their hazards cannot be ignored. On the one hand, fault phenomena such as arcs and sparks have e...
As the name suggests, the three-phase load reactor is a reactor used in three-phase power systems. Its core lies in its inductive characteristics, that is, when...
The LCL filter reactor is based on the traditional LC filter, by adding an inductance component (L2) and introducing advanced control strategies to form a doubl...
High-frequency noise and harmonics are two common harmful components in power electronic systems. High-frequency noise usually originates from the switching act...
Signal-to-Noise Ratio (SNR) is an important parameter to measure signal quality. It represents the ratio between useful signals and noise signals. During the si...
In the power system, the three-phase isolation transformer plays a vital role. The power system generates electricity from the generator, which is then boosted ...
