Answer
132 kV
Reason — The power generated at generating stations is transmitted at high voltages of 132 kV in order to reduce the loss of energy in the form of heat in the transmission line wires.

At the generating station, power is generated at :
- 33 kV
- 132 kV
- 11 kV
- none of the above
The electric power is generated at 11 kV because :
- voltage higher than 11 kV causes insulation difficulties
- voltage lower than 11 kV involves a very high current
- it reduces the loss of energy in the form of heat
- both (1) and (2)
