Synchronous transfer of auxiliary services at a generating plant or the motor load in an industrial plant is highly desirable to prevent either damage to critical motors or an unplanned shutdown. However, a significant induced voltage will remain at the terminals of a rotating machine for a period of time following removal of power. If, during the power transfer sequence, the phase angle of this voltage relative to the auxiliary source is ignored, severe damage to an expensive machine or process may result.

The M-0236B Power Transfer Relay provides a high-speed means to synchronously close a transfer breaker onto the disconnected but still spinning motor load, thereby avoiding damage to the machines. The maximum phase error at the instant of breaker closing is determined by slip rate and the breaker closing time.
