Question 11Electricity & Electronics - QMED

The correct answer is A) maintain rotor and stator winding temperatures above the dew point to prevent the formation of condensation. Space heaters are provided on larger generators to maintain the temperature of the rotor and stator windings above the dew point. This prevents the formation of condensation within the generator, which could lead to insulation breakdown and potential failure. Keeping the windings above the dew point ensures that moisture does not accumulate and cause issues. The other options, while related to preventing condensation, are not the primary reason for the space heaters on larger generators.
