When connecting compound generators in parallel, in order to prevent the possibility of unwanted load shifting, connect the series field of each machine to a common ____.
A) neutral plane
B) alternating bus
C) equivalent circuit
D) equalizer bus

Question

Quizplus · Accepted Answer

The equalizer bus is used to balance the voltage drops across the series field windings of each generator when they are connected in parallel. This prevents load shifting and ensures that each machine shares the load equally. Therefore, the best choice is D, the equalizer bus.
