NTPC Interview Questions, Process, and Tips

Turbines in thermal power plants are used to convert thermal energy into mechanical energy to generate electricity.

• Turbines are crucial components in thermal power plants for generating electricity

• They are driven by steam produced from the heat generated by burning fossil fuels

• There are different types of turbines used in thermal power plants such as steam turbines and gas turbines

• The turbines are connected to generato...read more

A sinusoidal wave is a type of wave that has a smooth, repetitive oscillation resembling a sine curve.

• Sinusoidal waves are characterized by their amplitude, frequency, and phase.

• They are commonly seen in AC electrical circuits, sound waves, and light waves.

• The equation for a sinusoidal wave is typically represented as y = A*sin(2*pi*f*t + phi), where A is the amplitude, f is the frequency, t is time, and phi is the pha...read more

Peak factor is the ratio of peak value to the RMS value of a waveform.

• Peak factor is used to quantify the peakiness of a waveform.

• It is calculated by dividing the peak value of the waveform by its RMS value.

• A higher peak factor indicates a more peaky waveform with larger peaks relative to the average value.

• Peak factor is important in signal processing and power systems analysis.

The stator and rotor are key components of an electric motor. The stator is the stationary part that generates a magnetic field, while the rotor is the rotating part that interacts with the magnetic field to produce motion.

• Stator is the stationary part of an electric motor

• Stator generates a magnetic field

• Rotor is the rotating part of an electric motor

• Rotor interacts with the magnetic field generated by the stator to pr

Measure miter, reducer, lateral at any degree by using a combination of mathematical calculations and physical measurements.

• Use a protractor to determine the angle of the miter, reducer, or lateral.

• Calculate the length of the pipe needed using trigonometry based on the angle and desired dimensions.

• Consider the pipe diameter and wall thickness when measuring for a reducer.

• Account for any additional fittings or weld allo...read more
