Capacitor Bank and its Circuit Breaker size calculation

hey welcome back to Rashid ibal channel in today's video I'm going to show you how to design and calculate a capacitor Bank a capacitor Bank also known as power factor correction panel is used for maintain an optimal power factor in electrical system simply we can say it reduce the amount of reactive power and

thus improve efficiency when your power factor is low your system use more electricity which increase your energy bill installing the capacitor panel helps improve the power factor reducing electricity consumption and avoiding extra charges from the utility company here you can see when you connect capacitor Bank to inductive load the reactive power decreases which reduce

the total apparent power as a result the power factor improves making the system more efficient before we jump into the calculation part let's understand the key parameters that affect the design of capacitor panel we need three important values number one total load in kilowatt this is the amount of active power your system is consuming second existing

power factor this is the current power factor of your system desire power factor this is the target you want to achieve typically it Clos to one sometime it's 0.95 97 98 depends on your requirement fourth one voltage the operating voltage of your system now let's take an example to understand understand this better here we have a

electrical system in which active power is 200 Kow system voltage 45 volt existing power VOR that is cos Theta 1 is 0.75 desired power factor that is cos theta2 = to 0.95 to calculate the required capacitor Bank size we use this formula QC = to P * tan Theta 1us tan Theta 2
