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.
