Tuned Harmonic Filters |
|
Technical Data
System Voltage : 400....660V
Filter tuned to : 5th,7th,11th,13th
Rated Kvar : 60....1800 Kvar
Type : Auto / fixed
Harmonic filter consist of other capacitors connected iw series with reactor. The capacitors produces reactive power at the filters fundamental frequency. A typical Harmonic filter consists of three series resonant circuits tuned to the most common harmonics ( 5th,7th,11th,harmonics). harmonic filters are custom designed for each application using standard components.This ensures that best possible power factor correction and filtering characteristics are standard components. This ensures that the best possible power factor correction and filtering characteristics are achieved with a reasonable investment. This will helps in reducing total harmonic distortion in the system as per Relevant standards like IEEES/9

Detuned Filters |
|
Technical Data
System Voltage : 400....950V
Resonant frequency :141 Hz and 189Hz
Rated Kvar : 25....5000 Kvar
Type : Auto / fixed
Detuned filter are designed to used for power factor correction in systems where harmonics are generated by nonlinear loads, each step of detuned filters consists of a capacitor and a series reactor connected in series. These two from a series resonant circuit tuned at a frequency below the lowest harmonics frequency present in the system normally the 5th (250Hz) . Detuned filter also removes lower order harmonics from the system to some extent. This will helps to offset the Resonance effect for longer trouble free operation.

Thyristor swithched capacitor banks |
|
Technical data:
system voltage : 400....690V Step Power : 50.....300 kVar
Rated kVar : 50.....1000kVar Swithching time : <40ms
Thyristor switched capacitor banks with high-speed switching capability are designed to support the supply voltage of distribution systems and to correct the power factor of connected loads. Thyristor switched are resistant to mechanical wear, operate without noise and are capable of practically transient-free switching. The minimum time the control unit needs for switching all the steps of the capacitor banks on/off is the period of only one cycle.

OSF ( Active Filters ) |
|
Technical Data:
System Voltage : 400....660V
Compensating current (r.m.s.) : 60A, 90A, 135A, 180A, 279A, 360A
Response time : <40ms Ambient temp. : 0 to 40C
The active filter is installed in parallel with the loads generate the harmonics. It analyses the harmonic current generated by these nonlinear loads and entire spectrum from the 2nd to the 25th harmonic, or for a specially targeted harmonic. This neutralizes the corresponding harmonic currents completely at the point of connection. This devices consists of one filter for each phase so that even highly a symmetric harmonics pollution can be suppressed, as well as the 3rd, 9th and 15th harmonics, which add together arithmetically in the neutral conductor,
