Dhoot Transmission Quality Engineer Interview Questions and Answers

Wind power generation converts wind energy into electricity using turbines, harnessing natural wind flow for sustainable energy.

• Wind turbines capture kinetic energy from wind.

• The rotor blades spin, turning a shaft connected to a generator.

• The generator converts mechanical energy into electrical energy.

• Electricity is transmitted through power lines to homes and businesses.

• Example: Offshore wind farms utilize strong sea

The supply process in a grid system involves generation, transmission, distribution, and consumption of electrical energy.

• 1. Generation: Electricity is generated at power plants using various sources like coal, natural gas, nuclear, or renewables (e.g., solar, wind).

• 2. Transmission: High-voltage transmission lines carry electricity over long distances to minimize energy loss.

• 3. Substations: Voltage is reduced at substa...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.

• When an AC current flows through the primary coil, it creates a magnetic field th...read more

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.

• The power formula is P = VI, where P is power, V is voltage, and I is current.

• Ohm's law is used to calculate the resistance of a circuit and to determine the amount of current flowing ...read more
