Refer to figures "1" and "2" of the basic synchronous transmission system shown in the illustration. Figure "1" shows a properly connected system where the receiver TR remains in correspondence with the transmitter TX. In figure "2", although properly zeroed, the receiver goes out of correspondence with the transmitter due to improper connections resulting in reverse torque direction. Which connection error results in this behavior? Illustration EL-0149

Question

Accepted Answer

Option A: A. Synchronous transmission systems rely on exact stator phase alignments between the transmitter and receiver. Connection error 'A' reverses excitation leads, causing opposing stator magnetic fields and generating a reverse torque that pulls the receiver out of correspondence.
