40. The slot electrical angle a1 is calculated as a1 = p × 360o / Z. It can be seen that the slot electrical angle a1 is equal to p times the slot mechanical angle am.

41. The principle of transformer winding reduction is: before and after the reduction, ensure that the magnetomotive force of the winding is constant, and that the active and reactive power of the winding are not changed.

42. The efficiency characteristic of a transformer is characterized by the existence of a maximum value, ie a maximum value when the variable loss is equal to the constant loss.
