Real Time Power Factor Control Panel

Real Time Power Factor Control Panel

We are engaged in offering technically advanced Real Time Power Factor Control Panel in the market. Real Time Power Factor Control Panel is modern power factor correction system having ability of correcting power factor in real time. Our Real Time Power Factor Control Panel is incorporated with high end measuring and complete harmonics free pollution and isolation circuits that are microcomputer based . We have equipped quickly responsive and advanced computing software in these panels.

Our Real Time Power Factor Control is designed the reactive power on real time basis for extremely rapid acquisitions of power factor. Connecting and Disconnecting of capacitor to and from network occurs a zero crossing, which smooth the connections of the circuit . This smooth connection avoids transient effects such as waveform distortions, generating of switching spikes etc.

Highlights :
  • Longer service
  • Incorporated with advanced technology
  • Low operating cost
  • Low maintenance

Details :
  • Our thyristor switching modules are built with state of the art switching circuits. The switching circuit continuously monitors voltage across thyristor and allows the thyristor to fire only & only if the voltage across the thyristor is zero. Thus the current through the thyristor always starts as if a normal load was switched on, and all the transients & switching pulses associated with other switching systems are totally absent.
  • Because of this we do not use any di/dt reactors. Since the switching is independent of the remnant charge on the capacitor, we do not need any fast discharge resistors or reactors.
  • Since switching in transients & pulses are totally absent, the capacitor life is enhanced several times. The entire system is saved from capacitor switching transients.
  • When harmonics are present, the conventional formula PF=Cos Ǿ is not valid. In such cases PF= Cos Ǿ X Distortion Factor (DF depends on extent of harmonic pollution and is less than 1. Therefore we do not use Cos Ǿ sensing relays. Instead we use KVAR controller.

Technical Specification :

    • For 240 V Phase to neutral configuration: 170V~ to 300V~
    • For 120V Line to Line configuration: 79V~ to 132V~

  • Current Input: 1A or 5A
  • Capacitor Voltage: 1A or 5A
  • 12V DC/20mA Solid state Output(Open Emitter) or Thyristor Switch Commands.
  • Rating from : 100- 1200 KVAR
  • Standard steps: 6 / 12.5/ 25 / 50 / 75 /100 KVAR
  • System included De-tuned iron core that de-tuned the network to prevent the resonance and absorb the harmonics.
  • Incomer- MCCB/ ACB
  • Capacitor- 450V / 525 V
  • Over temperature protection.

Salient Features :
  • The system is maintenance free because it does not use contactors for switching the capacitors.
  • Enhance the capacity of distribution transformer, switchgear and HT cable.
  • Power Factor will maintain almost near to unity so guaranteed P.F. bonus of 4 % to 5 % every month.
  • Capacitors life is enhance minimum 3 to 4 times. Due to electronics switching & rectors available in the system. The reactors will filter the harmonics & prevents the possibility of resonance by shifting resonance frequency below 5th harmonics.
