Medha Servo Drives Interview Questions, Process, and Tips

A 33/11kv transformer can be represented by a schematic diagram with two sets of windings and a core.

• The transformer has two sets of windings, one for the primary voltage of 33kv and the other for the secondary voltage of 11kv.

• The windings are wrapped around a core made of laminated steel to reduce energy loss due to eddy currents.

• The transformer may also have cooling fins or a cooling system to dissipate heat generate...read more

A circuit breaker is an electrical switch that automatically interrupts the flow of current when it exceeds a certain limit.

• It is used to protect electrical circuits from damage caused by overloading or short circuits.

• It works by detecting the excess current and tripping the switch to break the circuit.

• Once tripped, it can be reset manually or automatically depending on the type of circuit breaker.

• Common types include ...read more

DC motors and generators work on the principle of electromagnetic induction.

• DC motors convert electrical energy into mechanical energy

• DC generators convert mechanical energy into electrical energy

• Both use a commutator and brushes to switch the direction of current flow

• DC motors have a rotor and a stator, while DC generators have a stator and a rotor

• DC motors and generators have various applications in industries such a
