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

Stress-strain curve is a graphical representation of the relationship between stress and strain in a material.
It shows how a material behaves under stress and how it deforms under strain.
It is used to determine the elastic modulus, yield strength, and ultimate strength of a material.
The curve has three regions: elastic, plastic, and fracture.
Examples of materials with different stress-strain curves include rubber, stee
Iron carbon diagram is a graphical representation of the phases of iron-carbon alloys at different temperatures and carbon concentrations.
The diagram shows the relationship between carbon content, temperature, and the resulting microstructure of the alloy.
It is used to determine the properties of steel and cast iron.
The diagram consists of three regions: austenite, ferrite, and cementite.
