Correct option is A
Explanation:
Transmission voltages are standardized to ensure consistency, safety, and compatibility in power systems. The common standard transmission voltages include 132 kV, 400 kV, and 750 kV, among others. These are widely used for high-voltage transmission over long distances.
·
132 kV: Commonly used for regional transmission.
·
400 kV: Used for high-capacity transmission lines.
·
750 kV: Used in ultra-high voltage transmission systems in some countries.
222 kV is not a standard transmission voltage. Standard transmission voltages typically follow specific standard levels like 220 kV (which might be a source of confusion here), but 222 kV is not recognized as a standard voltage level in transmission systems.
Therefore, the correct answer is
(a) 222 kV.
