Tega Industries Senior Engineer Interview Questions and Answers

Q1. What is a resistor?
Ans. 
A resistor is an electronic component that resists the flow of electrical current.
• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and have color-coded bands to indicate their resistance value.

• Resistors dissipate energy in the form of heat when current flows through them.

• Common types of resistors include carbon film, metal film, and wirewound resistors.

Q4. What is PID and How does it work ?
Ans. 
PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in engineering.
• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• Proportional (P) control responds to the current error value.

• Integral (I) control accumulates past errors to correct the present error.

• Derivative (D) control predicts future errors bas...read more

Q6. Tell the interlock and permissive of boiler and turbine?
Ans. 
Interlocks and permissives are safety mechanisms in place to prevent unsafe operation of boiler and turbine systems.
• Interlocks prevent certain actions from taking place unless specific conditions are met

• Permissives allow certain actions to take place only if specific conditions are met

• Example of interlock: Boiler feed pump interlock prevents the boiler from starting unless the feed pump is running

• Example of permissive:...read more
