If you are asking about improving the power factor to decrease the surcharge you pay for having a low power factor you have to go about it like this.
Check your utility bill to find out what your existing power factor reading is. Power factor is the measure of how effectively your equipment converts electric current into useful power output.
The ratio of your usable power consumption in kilowatts to your reactive power consumption in kilo-vars determine your power factor.
When your power factor drops below 90%, a power factor surcharge is applied to cover the cost of supplying additional reactive power.
This usually applies to industrial and commercial buildings that have large and many motor loads. Inductive reactance from motors can be opposed by capacitive reactance. Adding capacitors to the system will improve your power factor which will bring your reading up to over 90%.
There are charts available where you can graph your existing reading and what you want to improve the power factor to. In the capacitor scale you are told how much capacitance has to be added to the system to get you to the higher reading.
On very large motors capacitors are added on the load side of the magnetic contactor so that when the motor is in operation the capacitors are in the motor circuit and when the motor's magnetic contactor drops out the capacitors also drop out of the circuit.

What else can I help you with?
What is characteristic of power factor in capacitor?
Power factor characteristic in a capacitor is a measurement of how efficiently a capacitor uses electrical energy.
How Capacitor functions as PF Corrector?
A capacitor functions as a power factor corrector by storing and releasing electrical energy to offset the reactive power drawn by inductive loads in a power system. When connected in parallel with the load, the capacitor supplies reactive power, improving the power factor and reducing overall system losses. This helps to improve efficiency, reduce voltage drops, and maximize the utilization of power distribution equipment.
Purpose of capacitor bank on a sub-station electrical room?
The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.
Why you use capacitors in power supply?
You use a capacitor to store electrostatic energy. You use an inductor to store electromagnetic energy. You use a resistor to dissipate electrical energy.
How do you connect the capacitor bank in electrical system?
improvement of power factor
What electrical component can hold a charge?
A capacitor is an electrical component that can hold an electrical charge. It stores energy in an electric field when connected to a power source and can release this stored energy when needed.
What is an AC capacitor and how does it function in electrical systems?
An AC capacitor is a component in electrical systems that stores and releases electrical energy. It helps to improve the efficiency and power factor of the system by providing a temporary boost of power when needed. The capacitor works by storing charge on its plates, which can then be discharged to help maintain a stable voltage and current flow in the circuit.
How Capacitor Banks works in Electrical System?
Capacitors used in delta connections so that they increase the power factor
Why you install capacitor bank in electrical room?
Capacitor banks are installed in the electrical room to improve the power factor which is related to the inductive load caused by motors etc . The capacitors create a capacitive load which subtracts against the inductive load thereby improving the power factor. Most power utilities have penalties when your power factor drops below a certain value.
How does a capacitor supply current to a bulb?
A capacitor supplies current to a bulb by storing and releasing electrical energy in the form of charges. When the capacitor is connected to the bulb, it discharges its stored energy, providing a temporary flow of current to power the bulb.
Why is use of capacitor in power system?
A capacitor in a power system is used 1.) to increase effective power factor, and 2.) to increase stability in response to transient load changes.Since the category is Electrical Engineering, answer 1 is probably more common, unless you are talking about a DC power supply.
What is a main filter capacitor?
A main filter capacitor is an electrical component used in power supply circuits to smooth out voltage fluctuations and reduce ripple in the output voltage. It is typically placed after the rectifier stage in a power supply, where it stores electrical energy and releases it as needed to maintain a steady voltage level. This helps ensure stable operation of electronic devices by providing a consistent power supply. The value and quality of the main filter capacitor are crucial for the performance and reliability of the power supply system.
