RTPFC is designed to compensate the reactive power on real time basis for extremely rapid acquisition of the power factor within the range of 40 - 60 msec. Connection and disconnection of the capacitor to and from the network occurs at zero crossing. This smooth connection avoids transient effects like waveform distortions, generation of switching spikes etc., typically created by electromechanically switched contactor based system. The response time of this is much higher than electromechanically switched systems.

This high-speed real-time Automatic Power Factor Correction Panel comes with suitable Tune and Detune harmonics filter. Venus technocrafts ensures that they compensate the reactive power required by any load requiring PF correction in a very short time (less than 20 ms), thereby reducing failure in sophisticated equipment. Maintaining unity PF, reduction in KVA demand, reduced electricity bills, enhanced capacity of transformer, switchgear, HT cable are few of the benefits accrued.

This state-of-the-art electronic switching device is primarily designed as a replacement of the electro-mechanically switched equipment. These systems while distinctly superior come with a price tag very comparable with the conventional switching APFC systems.

This type of Power factor correction is applicable in the industries like Steel, Forging , Welding, Press shop, Induction heating etc.

Detuned Reactor compensation equipments with electromechanical contactors, have a well proven performance in installation where the load has, slow variations and it is not very sensitive to voltage fluctuation. Today, however, more and more industrial installations, include electronic equipments that are very sensitive to voltage variations (PLC, computers, etc.) and also have very fast changing working cycles (automatic welding machines, robots, etc. ). Reactive power compensation with static contactors (Thyristor switch) offers the best answer to these new industry requirements. Venus Technocrafts installed automatic capacitor banks with static contractors, use thyristors instead of traditional contractors. The thyristors switch-on capacitors on zero crossing voltage, and switch them off on zero current situation. The firing strategy grants a totally transient free switching of power capacitors, avoiding any problems with transient over voltages. This firing strategy grants a totally transient free switching of power capacitors, avoiding any problems with transient over voltages. This transient free switching gives a very fast reaction time of the power factor equipments with sudden reactive power demand variations. This reaction time (the time to switch on or off a capacitor step) is usually not higher than 20 milliseconds. This means that upto 50 operations per second are possible.

APFC or Automatic Power Factor Control Panels are mainly used for the improvement of Power Factor.

Power Factor can be explained as ratio of active power to apparent power and it is a key factor in measuring electrical consumption. A dip in Power Factor can attract operational losses and a penalty from electricity board, also if the Power factor is maintained to Unity then the consumer can attract for incentive upto 7% in electricity bill. APFC Panels automatically manage quickly changing loads along with the retention of high Power Factor.

APFC stands for ‘automatic power factor correction’. An APFC panel consists of multiple capacitors of different ratings whose switching can be controlled as per requirement. An APFC is effective as a single-point installation which can be used to control the power factor for a large number of loads, instead of installing capacitors at the individual locations of each load.

Depending on the loads in operation, various levels of kVAR compensation are required to maintain proper power factor. The APFC panel contains a multi-step relay which is connected to multiple capacitors and a microprocessor controller which is programmed to control the switching operation of the relay. The voltage and current are measured on the feeder which is providing supply to the entire group of loads to determine the uncompensated power factor.
