Suzlon Group Junior Engineer Interview Questions and Answers

A circuit breaker is an electrical device that automatically interrupts the flow of current to prevent overloads and short circuits.

• Protects electrical circuits from damage due to overloads.

• Automatically resets after the fault is cleared in some types.

• Commonly used in residential and commercial electrical systems.

• Example: A circuit breaker trips when too many appliances are used simultaneously.

• Types include therma...read more

A thermistor is a temperature-sensitive resistor used for temperature measurement and control in various applications.

• Thermistors are made of ceramic materials that exhibit a significant change in resistance with temperature.

• There are two main types: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient).

• NTC thermistors decrease in resistance as temperature increases, commonly used in te...read more

Power curve is a graphical representation of the power output of a device or system over a range of operating conditions.

• Power curve shows the relationship between power output and operating conditions such as speed, load, or temperature.

• It helps in determining the optimal operating conditions for maximum power output.

• Power curves are commonly used in fields like engineering, renewable energy, and automotive indus...read more

Wind turbines convert wind energy into electrical energy.

• Wind turbines consist of blades, a rotor, a generator, and a tower.

• The blades capture the wind and turn the rotor.

• The rotor spins the generator, which produces electricity.

• The tower supports the turbine and raises it above the ground for better wind access.

• Wind turbines require consistent wind speeds of at least 6-9 mph to generate electricity.

• The electricit...read more

There are two main types of threads - internal threads and external threads.

• Internal threads are threads on the inside of a hole, while external threads are threads on the outside of a cylinder or cone.

• Common types of threads include metric threads, unified threads, and pipe threads.

• Threads can also vary in pitch, diameter, and shape depending on their intended use.

Gears are mechanical devices that transmit motion and power between rotating shafts. There are various types of gears including spur, helical, bevel, and worm gears.

• Gears are mechanical components with teeth that mesh with each other to transmit motion and power.

• Spur gears have straight teeth and are the most common type of gear.

• Helical gears have angled teeth for smoother and quieter operation.

• Bevel gears have co...read more
