Assertion (A): The stator winding of a control transformer has higher impedance per phase
Reason (R): The rotor of control transformer is cylindrical in shape.
The correct answer is option 'B', which states that both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
Explanation:
Control Transformers:
Control transformers are widely used in electrical and electronic equipment to step down voltage levels for control purposes. They are specifically designed to provide isolation and voltage transformation for control circuits.
Stator and Rotor Windings:
A control transformer consists of two windings, namely the stator winding and the rotor winding. The stator winding is the primary winding, which is connected to the supply voltage. The rotor winding is the secondary winding, which is connected to the load or control circuit.
Impedance of Stator Winding:
The stator winding of a control transformer has a higher impedance per phase compared to the rotor winding. This is because the stator winding is designed to handle the primary voltage and current, while the rotor winding is designed to handle the secondary voltage and current.
Explanation of Assertion (A):
The stator winding of a control transformer has a higher impedance per phase. This means that the stator winding has more resistance and reactance compared to the rotor winding. The higher impedance of the stator winding helps in limiting the fault current and provides better voltage regulation for the control circuit.
Explanation of Reason (R):
The rotor of a control transformer is cylindrical in shape. This shape allows for efficient magnetic coupling between the stator and rotor windings. The cylindrical shape of the rotor ensures a uniform distribution of magnetic flux, which helps in achieving a higher efficiency and better performance of the control transformer.
Explanation of Correct Answer (Option B):
Both Assertion (A) and Reason (R) are true. The stator winding of a control transformer does have a higher impedance per phase, and the rotor of a control transformer is indeed cylindrical in shape. Furthermore, Reason (R) is the correct explanation of Assertion (A. The cylindrical shape of the rotor helps in achieving efficient magnetic coupling and contributes to the overall performance of the control transformer.
Reason (R): The rotor of control transformer is cylindrical in shape.
The correct answer is option 'B', which states that both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
