Adani Group Senior Assistant Mechanical Manager Interview Questions and Answers

A transformer operates on electromagnetic induction to transfer electrical energy between circuits at different voltage levels.

• Consists of primary and secondary coils wound around a magnetic core.

• Works on the principle of Faraday's law of electromagnetic induction.

• When alternating current flows through the primary coil, it creates a magnetic field.

• This magnetic field induces a voltage in the secondary coil.

• Transformers...read more

The efficiency of a transformer measures how effectively it converts input power to output power, typically expressed as a percentage.

• Efficiency is calculated as (Output Power / Input Power) x 100%.

• Typical transformer efficiencies range from 95% to 99%.

• Higher efficiency reduces energy losses, making transformers more economical.

• Example: A transformer with 98% efficiency means 98% of input power is converted to output p...read more

Power plants generate electricity using various energy sources, including fossil fuels, nuclear, and renewables.

• Thermal Power Plants: Use fossil fuels like coal, oil, or natural gas (e.g., coal-fired plants).

• Nuclear Power Plants: Generate electricity through nuclear fission (e.g., plants using uranium).

• Hydroelectric Power Plants: Utilize flowing water to generate power (e.g., Hoover Dam).

• Wind Power Plants: Harness wind...read more

A hybrid system combines different technologies or methodologies to leverage their strengths for improved performance and flexibility.

• Hybrid systems can integrate both analog and digital components, such as in hybrid cars that use both electric and gasoline engines.

• In computing, hybrid systems may refer to cloud computing models that combine public and private clouds for enhanced scalability and security.

• In control sys...read more

Transformers are electrical devices that transfer energy between circuits through electromagnetic induction, with various types for different applications.

• Step-up Transformer: Increases voltage, used in power transmission.

• Step-down Transformer: Decreases voltage, used in power distribution.

• Isolation Transformer: Provides electrical isolation, used in sensitive equipment.

• Auto Transformer: Has a single winding, used for ...read more

A central inverter converts DC electricity from solar panels into AC electricity for grid use or consumption.

• Central inverters are commonly used in large-scale solar power plants.

• They are more efficient for larger installations compared to string inverters.

• Examples include the SMA Sunny Central and ABB PVS series.

• Central inverters typically require more space and are installed in dedicated areas.

• They can manage multipl...read more
