Power Factor Capacitor

Advantages of 96-100% Power Factor 

1. Increase in efficiency of system and devices.
2. Low Voltage Drop.
3. Reduction in size of a conductor which reduces the cost of the Cooper.
4. An Increase in available power.
5. Line Losses (Copper Losses) I2R is reduced.
6. Improved voltage to equipment
7. Reduce power losses thus Lower the electric bills.

The most common and economical solution to correcting poor power factor is to install capacitors. Capacitors have been used to correct poor power factor since 1917.   Capacitors act as a temporary storage bank for kVAR, thus consumers no longer receive their reactive power from the utility but from the capacitor bank that is located within their facility. This has no effect on the kW or real power but reduces kVA or apparent power as the kVAR has been reduced from the utility.

WHAT IS POWER FACTOR?
Power Factor is a measure of how efficiently electrical power is consumed. In the ideal world Power Factor would be unity (or 1). Unfortunately in the real world Power Factor is reduced by highly inductive loads to 0.7 or less. This induction is caused by equipment such as lightly loaded electric motors, luminaire transformers, and fluorescent lighting ballasts and welding sets, etc. Power Factor is reflected in the Meralco Electric bill if there is NO power factor in your electric bill, you do not need power factor capacitor.  The power factor shown above is 82.43%. The ideal power factor is              96-100%. - Engr Roland Manansala
WHAT DOES IT DO TO MY ELECTRICITY BILL?
In a 3 phase supply, kW consumed is (VOLTS x AMPS x 1.73 x Power Factor) / 1000. The Electricity Company supply you VOLTS x AMPS and they have to supply extra to make up for the loss caused by poor Power Factor. When the power factor falls below a set figure, the electricity supply companies charge a premium on the kW being consumed, or, charge for the whole supply as kVA. You received the ff: Penalty - 1.4% surcharge for every percentage point lower than 85% Discount - 0.7% for every percentage point higher than 85%  Email your photographed Meralco bill to engr.manansala@gmail.com and I will email back a complete proposal - Engr Roland Manansala
WHAT CAUSES POWER FACTOR TO CHANGE?
Inductive loads cause the AMPS to lag behind the VOLTS. The waveforms of VOLTS and AMPS are then "out of phase" with each other. The more out of phase they become then the lower the Power Factor. Power Factor is usually expressed as Cos Phi. (Ø)
	In 3 phase power supplies, the "power" can be measured as a triangle.  ACTIVE Power is the baseline and is the real usable power measured in kW. REACTIVE power is the vertical or that part of the supply which causes the inductive load. The reactive power in is measured in kVAr (kilo volt-amperes reactive) APPARENT Power is the hypotenuse. This is the resultant of the other two components and is measured in kVA
THE EFFECTS OF POWER FACTOR.
Consider a canal boat being pulled by a horse. If the horse could walk on water then the angle (Phi) Ø would be zero and COSINE Ø=1. Meaning all the horsepower is being used to pull the load.  However, the relative position of the horse influences the power. As the horse gets closer to the barge, angle Ø1 increases and power is wasted, but, as the horse is positioned further away, then angle Ø2 gets closer to zero and less power is wasted
WHY DO I NEED POWER FACTOR CORRECTION?
Capacitive Power Factor correction (PFC) is applied to electric circuits as a means of minimizing the inductive component of the current and thereby reducing the losses in the supply.  The introduction of Power Factor Correction capacitors is a widely recognised method of reducing an electrical load, thus minimizing wasted energy and hence improving the efficiency of a plant and reducing the electricity bill. It is not usually necessary to reach unity, ie Power Factor 1 since most supply companies are happy with a PF of 0.95 to 0.98 BIG monthly Peso savings, R.O.I. is normally less than one year.   Power Capacitor's expected life is 10 years. - Engr Roland Manansala
HOW DOES IT WORK?
By installing suitably sized switched capacitors into the circuit, the Power Factor is improved and the value becomes nearer to 1 thus minimizing wasted energy and improving the efficiency of a plant  This is NOT applicable to residential loads, single phase.  This is the ONLY electrical system equipment that is in Electrical Engineering books and approved by Meralco. After installing the power capacitor, we will write a letter to inform Meralco of our installation.  - Engr Roland Manansala
