Interview Questionnaire
12 Questions
- Q1. Questions related to internship, projects done in college.
- Q2. Which one is more efficient for railways- 750V DC or 25 KV AC..and why?
- Q3. Some questions related to catenary.
- Q4. Induction motor speed torques curve and some derivations on that.
- Ans.
The speed-torque curve of an induction motor describes the relationship between motor speed and torque.
The speed-torque curve shows how the motor's torque output varies with changes in speed.
At low speeds, the motor can produce high torque, but as the speed increases, the torque decreases.
The curve typically has a peak torque value called the breakdown torque.
Beyond the breakdown torque, the motor enters the field weak...
- Q5. 2 Programming questions..I don't remember the questions but they asked to write complete code.
- Q6. 1 question based on volatge rating of 3 phase fully controlled inverter.
- Ans.
Understanding voltage ratings in a 3-phase fully controlled inverter is crucial for efficient power conversion.
A 3-phase fully controlled inverter uses thyristors to convert DC to AC.
The voltage rating is determined by the maximum DC input voltage and the inverter's design.
For example, if the DC input is 600V, the output AC voltage can be approximately 0.9 times the DC voltage.
The inverter's voltage rating must also co...
- Q7. Why induction motor is replacing DC motor for traction purpose?
- Ans.
Induction motors are replacing DC motors for traction purposes due to their higher efficiency, lower maintenance, and simpler control.
Induction motors have higher efficiency compared to DC motors, resulting in reduced energy consumption.
Induction motors require less maintenance as they have no brushes or commutators that wear out over time.
Induction motors have simpler control systems, making them easier to operate and...
