✓

Direct Answer

Option D: All of the above

All major power generators regardless of prime mover type require overvoltage protection to protect stator insulation from lightning, switching surges, and load rejection overvoltages.

All Options

Hydro-electric generators

Steam turbine generators

Gas turbine and diesel generators

All of the above (Correct Answer)

Detailed Explanation & Context

All major power generators regardless of prime mover type require overvoltage protection to protect stator insulation from lightning, switching surges, and load rejection overvoltages.
