(3 Questions)

  • Q1. *Why Transformer Rated In kVA, Not in KW? *What are transformer losses & their types?
  • Ans. 

    Transformers are rated in kVA because it takes into account both active power (KW) and reactive power (KVAR). Transformer losses include copper losses and iron losses.

    • Transformers are rated in kVA because they handle both active power (KW) and reactive power (KVAR).

    • kVA rating considers the total power (apparent power) that the transformer can handle, including the power needed for magnetizing the core.

  • Q2. *Mention what is the difference between generator and alternator? *Mention what are the different kind of cables used for transmissions?
  • Ans. 

    Generator produces direct current while alternator produces alternating current. Different cables used for transmission include coaxial, twisted pair, and fiber optic cables.

    • Generator produces direct current (DC) while alternator produces alternating current (AC)

    • Generator uses slip rings and brushes for transmission while alternator uses a commutator

    • Different cables used for transmission include coaxial, twisted pair,

  • Answered by AI
  • Q3. Define the principle of motors?
  • Ans. 

    Motors operate based on the principle of electromagnetic induction, converting electrical energy into mechanical energy.

    • Motors work by creating a magnetic field through the flow of current in a coil of wire.

    • This magnetic field interacts with a permanent magnet or another magnetic field, causing the coil to rotate.

    • The rotation of the coil is then used to drive mechanical systems, such as fans, pumps, or conveyor belts.
