Autotransformer starters, sometimes called starting compensators, are sometimes used with larger polyphase induction motors. What function do they perform?
A
they allow the voltage to be either stepped up or down, depending on the application, to ensure full torque
B
they increase the voltage for "across-the-line starting"
C
they provide a backup means of voltage regulation for emergency starting
D
they reduce the voltage applied to the motor during the starting period
