Samsung E&A Graduate Engineer Interview Questions and Answers

Q1. Different transformer protection
Ans. 
Different transformer protection methods include overcurrent protection, differential protection, and distance protection.
• Overcurrent protection: Protects against overloads and short circuits by tripping the circuit breaker when current exceeds a certain threshold.

• Differential protection: Compares the current entering and leaving the transformer to detect internal faults.

• Distance protection: Uses impedance measurements...read more

Q2. Variable frequency drive working
Ans. 
Variable frequency drive (VFD) controls the speed of an electric motor by varying the frequency and voltage of the power supplied to it.
• VFDs are commonly used in industrial applications to control the speed of pumps, fans, compressors, and other motor-driven equipment.

• They work by converting fixed frequency AC power to variable frequency AC power using semiconductor devices.

• VFDs can improve energy efficiency, reduce we...read more

Q3. Speed control of motor
Ans. 
Speed control of a motor is achieved by varying the voltage or frequency of the power supply.
• Speed control can be achieved by adjusting the voltage supplied to the motor.

• Alternatively, the frequency of the power supply can be varied to control the speed.

• Using a variable frequency drive (VFD) allows for precise control of motor speed.

• Feedback control systems can be implemented to maintain a constant speed under varying

Q4. What is Finite Element Analysis? Explain using examples.
Ans. 
Finite Element Analysis is a numerical method used to solve complex engineering problems by dividing them into smaller, simpler parts.
• It involves breaking down a complex structure into smaller elements and analyzing each element separately.

• The results of each element are then combined to obtain the overall behavior of the structure.

• FEA is used in various fields such as aerospace, automotive, civil, and mechanical engin...read more

Q5. What is ductility of a metal? Does temperature have any effect on a metal's ductility?
Ans. 
Ductility is the ability of a metal to deform under tensile stress. Temperature affects ductility.
• Ductility is the measure of a metal's ability to stretch without breaking.

• Metals with high ductility can be drawn into wires or hammered into thin sheets.

• Temperature affects ductility, as heating a metal can increase its ductility while cooling it can decrease it.

• For example, copper is highly ductile and can be easily draw...read more
