CESC Interview Questions, Process, and Tips

Induction Motor equivalent circuit consists of stator and rotor circuits with mutual induction.

• The stator circuit includes three-phase winding and a power source.

• The rotor circuit includes rotor winding and a short-circuited conductor.

• The mutual induction between stator and rotor circuits causes the rotor to rotate.

• The equivalent circuit can be represented using a circuit diagram with resistances, inductances, and mutu...read more

B-H curve is a graph that shows the relationship between magnetic field strength and magnetic flux density.

• B-H curve is used to characterize the magnetic properties of a material.

• It is a plot of magnetic flux density (B) versus magnetic field strength (H).

• The slope of the curve at any point is the permeability of the material at that point.

• The curve can be used to determine the saturation point of a material.

• Examples o...read more
