  • Q1. What is Transformer?
  • Ans. 

    A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

    • Consists of two coils of wire, known as primary and secondary coils

    • Works on the principle of electromagnetic induction

    • Used to step up or step down voltage levels in electrical circuits

    • Commonly used in power distribution systems

  • Answered by AI
  • Q2. What is transformer Protection
  • Ans. 

    Transformer protection refers to the measures taken to prevent damage to transformers from faults or abnormal operating conditions.

  • Q5. How much torque a synchronous motor can develop?
  • Ans. 

    The torque a synchronous motor can develop depends on its size and design.

    • The torque is directly proportional to the current supplied to the motor.

    • The torque also depends on the strength of the magnetic field produced by the rotor.

    • Larger synchronous motors can develop higher torque than smaller ones.

    • For example, a 500 kW synchronous motor can develop a torque of around 1500 Nm.

    • The torque can also be affected by factors
