How to Change the Capacitor in a Ceiling Fan?

It can be done very swiftly by following the given steps:

Step 1: At first, disconnect the power supply by switching off the main circuit breaker in the home distribution board.

Step 2: Now, cut the wires that are connected to the faulty capacitor and remove it.

Step 3: Then take a new capacitor and connect the red wire from the fan to the first terminal of the capacitor and the second terminal with the blue wire.

Step 4: Put a wire nut and electric tap and insert both the wires.

Step 5: Connect the neutral wire (the black color wire) from the fan to the second slot of the wire connector.

Step 6: Now take the neutral and the live wire and connect it to the power supply. Finally, switch ON the primary circuit and test the fan.

Importance of Capacitor in Ceiling Fans  

A capacitor is a basic instrument required to make a complete electric circuit. Besides this, a complete circuit also needs other necessary tools like transistors, resistors, diodes, inductors, etc. to work properly. A capacitor is also called a condenser.

The primary purpose of a capacitor is to store the electrical energy under the influence of an electric field and then transfer the electric energy to the circuit. A capacitor does not allow the flowing of direct current (DC) to pass through it to avoid any harmful breakdown in the circuit but allows the alternative current (AC) to pass through it.

There are several benefits of using a capacitor in any circuit:

  • Capacitors are significantly less sensitive in response to any change in temperature.
  • It supports AC (alternative current).
  • To avoid accidents, they can be discharged very easily and quickly.
  • A capacitor can withstand even a very high voltage.
  • A capacitor can have very long durability.
  • It is capable of filtering out any unwanted frequency very effectively.
  • It is capable of working with high frequencies.
  • It can store electrical energy within a circuit and distribute that electrical energy when required.

Frequently Asked Questions 

1) What is the recharging capability of a capacitor?

Actually, there is no specific practical limit available to recharge and know the capability of a capacitor. It could be charged just after as soon as it is discharged. So power rating for the rectifier, Direct current to Direct current converter, or any recharging types of equipment are the limiting factors. The listed maximum current or pulse current can highlight its high power density.

2) How can we determine the SOC or the State Of Charge?

State of Charge (SOC) is the amount of stored energy that is compared to the most significant amount of energy that can be reserved by it. Compared to batteries in capacitors, it is easier to determine the State Of Charge. The energy stored in the capacitor is directly proportional to the voltage square, that is, energy stored = Voltage^2 * ½ Capacitance.

To calculate the State Of Charge, we have to divide the square of the measured voltage by the square of the designed voltage. For e.g., any system designed by a float voltage 480 V and that is currently showing at 400 V. Then its State Of Charge would be 69 Percent.

3) Can I pair a capacitor with a battery?

Yes, pairing any capacitor or capacitors with batteries would create a HESS, that is, a Hybrid Energy Storage System. It can provide a solution for optimal energy storage in terms of power density, energy density, and the whole system’s lifetime. By this, the total cost of the ownership could be improved.

A multiple-input PCS, the Power conditioning System, uses this application to integrate the two technologies into the passive configuration by directly placing the two technologies in an active system or in a parallel arrangement.

4) What is the difference between capacitors and supercapacitors?

Both the supercapacitor and capacitor store electrostatic charge, but its material is different. Generally, flat plates are used to store electrostatic charge in a regular capacitor. The larger the surface area of the plates, the higher will be the capacitance of the capacitor, and this tends to increase in its sizes. But in Supercapacitors, such a material is used for storing charge can offer a large surface area. It can reserve such a high electrostatic charge for very high capacitance and within a small package.

The Bottom Line

Though in today’s life, we have improved a lot in the field of technology, most of us are still unaware of how it is working. Actually, in our daily busy life, we all are happy and satisfied with the impressive results of various technologies. But if we can know about how they are working, then we can easily maintain its usage and increase its duty cycle and durability.
