Transformers specifications include power rating, voltage ratio, impedance, cooling method, and insulation class.

• Power rating determines the maximum amount of power a transformer can handle.

• Voltage ratio defines the ratio between the primary and secondary voltages.

• Impedance indicates the resistance to the flow of current in the transformer.

• Cooling method can be air, oil, or water-cooled, depending on the transformer's ...read more

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...read more

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
