Schneider Electric Diploma Trainee Engineer Interview Questions and Answers

Q1. DC motor working?
Ans. 
DC motor converts electrical energy into mechanical energy through the interaction of magnetic fields.
• DC motor operates based on the principle of Lorentz force

• It consists of a stator (field) and a rotor (armature)

• When current flows through the armature winding, a magnetic field is created which interacts with the stator field to produce rotational motion

• Speed of DC motor can be controlled by varying the voltage or curr...read more

Q1. Transformers losses to be defined
Ans. 
Transformers losses refer to the energy lost in the transformer during the process of converting electrical energy from one voltage level to another.
• Transformers losses can be broadly classified into two categories - copper losses and iron losses.

• Copper losses occur due to the resistance of the transformer windings and are also known as I²R losses.

• Iron losses occur due to the magnetic properties of the core material an...read more
