Filter Banks

Automatic Harmonic Filter Banks

Approx Price: Rs 1,000 / Piece 
Automatic Harmonic Filter Banks are suitable for plants and installations, where load on the power system is fluctuating. In this type of bank, the total kva is divided into a number of steps equal or unequal- depending upon the load conditions. The capacitor steps are switched in or out through a contactor, controlled by a power factor controller of type MCX. If a discharge coil (Voltage Transformer) is connected along with the steps, the discharge time of capacitors get reduced to 10 seconds (otherwise it is 10 minutes). This would enable rapid reconnection of steps. These banks are equipped with:

  • Sheet metal enclosure.
  • H.R.C. Fuses for capacitor steps with fuse failure indication.
  • Vacuum contactor or SF6 circuit breaker.
  • Inrush current limiting reactor (inductor).
  • H.V. Capacitor units of single phase or three phase AB LIFASA with internal element fuses.
  • Control box with power factor controller and indications.

 

    Product Range:

    • 50 kva to any rating as per the requirement of customer.
    • Voltage rating up to 36 kva.

     

      Designs and specifications:

      • With vast knowledge and experience available in AB lifasa, we are capable of working out a technically and economically viable power factor solution for each type of installation.

      Application of Active Harmonic Filter:

      • This is the ideal solution for installations with a large amount of the single-phase and three-phase loads generating harmonics such as computers, the UPC, lights lifting equipment.

      Advantage of Active Harmonic Filter:

      • Bolts and outlet to ensure the reliability and stability of the wiring, to meet the requirements of large-capacity, high current.
      • Safe and reliable American pressure explosion-proof structure, built-in discharge resistor, making the product safer and more reliable.
      • Long-life, multi-component designs to increase the cooling area, the lower the temperature rise of the capacitor, to extend the life of the capacitor.
      • Capacitor components with special metalized film side blocking both high self-healing properties, but also meets the requirements of high reliability contacts and high-pressure.
      • Safe and effective protective measures to remove the injury to the human body.
      • Convenient and reliable installation, improve work efficiency.

      Typical Customer:

      • Small industries of all kind
      • Power utilities
      • Contractors
      • Small commercial premises
