Top 10 Questions for Electro-Mechanical Technician (E/M Technician) Interview

Essential Interview Questions For Electro-Mechanical Technician (E/M Technician)

1. Explain the working principle of a three-phase induction motor?

The three-phase induction motor works on the principle of electromagnetic induction. It consists of a stator with three-phase windings and a rotor with conductors. When the three-phase supply is given to the stator windings, a rotating magnetic field is produced. This rotating magnetic field induces an electromotive force (EMF) in the rotor conductors, which in turn causes a current to flow in the rotor conductors. The interaction between the rotating magnetic field and the current-carrying rotor conductors produces torque, which causes the rotor to rotate in the same direction as the rotating magnetic field.

2. What are the different types of electrical faults that can occur in a power system?

Overcurrent fault

  • Overcurrent fault occurs when the current in a circuit exceeds the safe carrying capacity of the conductor.
  • This can be caused by a short circuit, overload, or ground fault.

Short circuit fault

  • A short circuit fault occurs when two conductors with different potentials come into contact with each other.
  • This causes a large current to flow through the fault, which can damage equipment and cause a power outage.

Ground fault

  • A ground fault occurs when a conductor comes into contact with the ground.
  • This can cause a current to flow through the ground, which can damage equipment and cause a power outage.

Open circuit fault

  • An open circuit fault occurs when a conductor is broken or disconnected.
  • This causes the current in the circuit to stop flowing, which can prevent equipment from operating.

3. What are the different types of electrical protection devices used in power systems?

  • Fuses
  • Circuit breakers
  • Relays
  • Surge protectors
  • Ground fault interrupters (GFIs)

4. What are the different types of electrical test equipment used to troubleshoot electrical systems?

  • Multimeters
  • Clamp meters
  • Insulation testers
  • Ground resistance testers
