Marine Electricals Automation Engineer Interview Questions and Answers

Updated 7 Oct 2021

9 Interview questions

An Automation Engineer was asked
Q. How do you calculate power factor?
Ans. 

Power factor is the ratio of real power to apparent power in an AC circuit.

  • Power factor = Real power / Apparent power

  • It is measured in a scale of 0 to 1 or 0 to 100%

  • A power factor of 1 means all the power is being used efficiently

  • A power factor of less than 1 means some power is being wasted

  • Capacitors can be used to improve power factor

An Automation Engineer was asked
Q. How do you select a VFD based on the motor?
Ans. 

VFD selection depends on motor voltage, current, and power rating.

  • Check motor nameplate data for voltage, current, and power rating

  • Select VFD with compatible voltage and current rating

  • Ensure VFD power rating is equal to or greater than motor power rating

  • Consider additional features such as overload protection and communication protocols

  • Consult manufacturer's specifications and guidelines

An Automation Engineer was asked
Q. What is VFD?
Ans. 

VFD stands for Variable Frequency Drive.

  • It is an electronic device that controls the speed of an AC motor by varying the frequency of the electrical supply to the motor.

  • It is used to save energy and improve process control in industrial applications.

  • VFDs are commonly used in HVAC systems, pumps, fans, and conveyors.

  • They can also be used to control the speed of electric vehicles and wind turbines.

An Automation Engineer was asked
Q. What is SCADA?
Ans. 

SCADA stands for Supervisory Control and Data Acquisition. It is a system used for monitoring and controlling industrial processes.

  • SCADA systems are used in various industries such as oil and gas, water treatment, and manufacturing.

  • They collect data from sensors and other devices and display it in a graphical interface for operators to monitor.

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
