FILTER REACTOR ADVANTAGE AND USES

​

Description

The used of current source inverters and converters is increasing continuously, causing harmonics that results in additional losses, particularly in capacitor for power factor correction systems.

 

Key Benefits

• Avoidance of Resonance conditions.

• Tuned & Detuned Harmonic filters.

• Reduction of Harmonic Distortion (Network clearing)

Salient Features

• High Harmonic loading capability.

• High Linearity.

• Low Noise.

• Low Losses

• Convenient Mounting.

• Long Life Time.

 

Filtering with MH harmonic circuit filter reactor provides the following advantages :

• reduce losses ; hence no capacitor overload

• impedance behavior of the mains is improved

Filter Reactors

Filter Reactors are used in conjunction with capacitor banks to form series tuned harmonic filter circuits, or in conjunction with capacitor banks and resistors to form broadband harmonic filter circuits. When specifying filter reactors, the magnitudes of fundamental and harmonic frequency current should be indicated. If inductance adjustment for fine-tuning is required, the required tapping range and tolerance must be specified.

 

Many filter applications require a Q factor that is much lower than the natural Q of the reactor. This is often achieved by connecting a resistor in the circuit. 
An economical alternative is the addition of a de-Q'ing ring structure on a reactor. This can reduce the Q factor of the reactor by a significant amount without the necessity of installing additional damping resistors. 
These rings, mounted on the reactor, are easily coupled to the magnetic field of the reactor. This eliminates the concern of space, connection and reliability of additional components such as resistors.
