Description

General description:

The increasing use of modern power electronic  apparatus that  produce non-liner current influences and loads the  network with harmonics pollution, the capacitor forms a resonant with the feeding transformer by a self-resonant frequency between 250Hz to 500Hz,    it leads to  the following undesirable problems: 

overloading  of capacitor  and transformer,  interference with metering and control device, computer and electric gear system , voltage distortion, amplification harmonics.These problems can be avoided by connecting the detuned/filter reactors.

 

Features:

1.Non-flammable

2.Low loss and low noise

3.High resistance to harmonic&high linearty

4.Long use life

 

Basic Calculations

Harmonic Load(continuous)

U3=0.5%UR

U5=5.0%UR

U7=5.0%UR

Fundamental Harmonic Load

I1=1.06 IR(IR=current of the fundamental harmonic)

Terminal Rating

Ith=1.05 Irms

Magnetic rating

Ith=1.75 L with L(Lin) ≧0.95Ln

Self-resonant Frequency

Detuned system are scaled so that the self-resonant frequency is below the lowest line harmonics system

Applications

>Automatic power factor correction(PFC) and capacitor banks
>Fixed power factor corrections individual (e.g.motor, transformers, lighting, etc)
>Group fixed power factor correction (several equipments connected in a group)
>Capacitor banks of tuned and detuned.
>Harmonic trap applications (e.g.UPS, frequency drives and converters, etc)
