The power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses. Displacement PF is defined as the cosine of the angle between fundamental voltage and fundamental current of the load. The presence of Harmonics increases the RMS current and voltage relative to their respective fundamental values. This increases the KVA of the Load. The Power Factor correction capacitor taking into account the effect of the Harmonics is called the true power factor..
True PF ≤ Displacement of the factor by which Displacement PF is related to the True PF is called the Distortion PF
What is Power Factor Correction Capacitor
The power factor of your installations can be improved by the placement of power factor capacitors where they work as reactive generators of power. This is required when you notice that the apparent current is superior to the working current that you are getting.
Only Power Factor Correction Capacitors can improve Displacement in Power Factor
The application of shunt capacitors to industrial power systems has several benefits. Among these are:
Benefit 1 — Reduce Power Bills
Benefit 2 — Gains in System Capacity
Benefit 3 — Improve Voltage Conditions
Benefit 4 — Reduce Line Losses
Listed below are various installation options. Care must be taken in sizing and placing power factor correction capacitors. Leading power factor, greater than 100%, must be avoided. The capacitors should only be online when the load requires kVAR and disconnected when the load is reduced.
Where do you need to install these capacitors?
You may be thinking about where to install these capacitors for having the best result. We not only supply you with the best capacitors but also help you in the proper installation of those. The ideal places to use these capacitors are:
If you find that load that is applied is continuous in nature and it is stable, then the capacitors are placed in the main LV distribution board that you have. There are various advantages that you can have from such installation as:
Reduction in penalties regarding traffic for the consumption of kvars which is excessive
It helps in reduction of KVA demand for apparent current.
It helps in making the supply transformer free so that it can take up more load.
If you have a huge installation where the load/time pattern differs from sector to sector, then the capacitors need to be fitted with the bus bars that are present at the local board for distribution. The advantages that can be achieved are:
Reduction in penalties regarding traffic for the consumption of kvars which is excessive
It helps in reduction of KVA demand for apparent current.
It helps in making the supply transformer free so that it can take up more load.
The supply cable size can be reduced
There will be a reduction in the loss that happens in the cables.
If you see that the power that is used by the motor is significant if compared with the power that you have in the installation, then these capacitors are connected to the terminals to have the desired result. The advantages that can be achieved in such a case are:
Reduction in penalties regarding traffic for the consumption of kvars which is excessive
Power Factor Correction helps in reduction of KVA demand for apparent current.
Cable size and loss in the cable can also be reduced by such implementation.
