  Problem Answer
1 A cumulative compound interpole motor connected for operation in a clockwise direction is to be driven as a cumulative compound generator in a counter-clockwise direction with reversed polarity. Give instructions for making necessary changes without reversing the remanent magnetism.  
2 A cumulative Compound interpole, self-excited generator is to be used as a cumulative compound motor in the same direction of rotation. Give instructions for making necessary changes in connections.  
3 Two compound generators in parallel are used to energize a factory power line. The driving engine of one generator is stopped before the generator is disconnected from the line. Analyze the probable results.
