Description
This setpoint adjusts maximum absolute value of difference between actual
phase angle between the bus and mains voltages for synchronizing.

OTE
:
To disable issuing the breaker close command (i.e. for test purpose) adjust
this setpoint to 0. Synchronizing will continue until timeout occurs or the
breaker is closed externally.
N
OTE
:
The setpoint works as a window surrounding the BtoM AngleReq setpoint.
E.g. for BtoM AngleReq = +30° and Phase window = 5°, the breaker closure
is allowed for 25° to +35°.
If you want to lock out the breaker closing during synchronizing control loop
test, set Phase window = 0. This allows the control loop setpoints to be tuned
while actual breaker closing is blocked.
