Reactive power results in what effect on a generator?

Explanation:
Reactive power increases the current you have to supply for the same amount of real power. That extra current flows through the generator windings, causing more copper losses (I^2R losses) and more heat. The generator then runs hotter, which pushes its thermal limits, can reduce efficiency, and shorten component life or reliability over time. So reactive power makes a generator hotter and less reliable/efficient. It doesn’t improve efficiency, and it does cause a change in temperature, not no change.
