Power is the rate at which work is done or energy is transferred. A power plant converts fuel into electrical energy.
Power is measured in watts or kilowatts.
A power plant works by converting fuel into heat, which is then used to generate steam to turn a turbine and produce electricity.
There are different types of power plants such as coal-fired, nuclear, hydroelectric, and renewable energy plants.
Power factor is the ra...
The power triangle is a graphical representation of the relationship between real power, reactive power, and apparent power in an AC circuit.
Real power is represented by the horizontal leg of the triangle.
Reactive power is represented by the vertical leg of the triangle.
Apparent power is represented by the hypotenuse of the triangle.
The angle between the horizontal leg and the hypotenuse is the power factor angle.
The p...
Phase angle is the difference in phase between two waveforms.
Phase angle is measured in degrees or radians.
It is used to describe the relationship between two waveforms.
It is important in fields such as electrical engineering and physics.
For example, in AC circuits, the phase angle between voltage and current determines the power factor.
Calculate total power consumption given a problem
Determine the power consumption of each device
Add up the power consumption of all devices
Consider the time period over which power is consumed
Account for any inefficiencies or losses in the system

A single line diagram is a simplified representation of a power system.
A single line diagram shows the electrical components of a power system in a simplified manner.
It is used to understand the flow of power and to identify potential problems.
It includes generators, transformers, transmission lines, distribution lines, and loads.
Each component is represented by a symbol and connected by lines to show the flow of power...
Voltage compensation at load centre
Voltage drop occurs in the distribution system due to the resistance of the conductors
Voltage compensation is done to maintain the voltage level at the load center
Methods of voltage compensation include tap changing transformers, voltage regulators, and shunt capacitors
To increase voltage for running tubewell when voltage is low, use a voltage booster or stabilizer.
Use a voltage booster or stabilizer to increase voltage
Check for any loose connections or damaged wires
Ensure the tubewell motor is not overloaded
Consider installing a capacitor bank to improve power factor
Consult with an electrician if necessary
