considered an under voltage condition. It should be handled by
configuring the under voltage alarm functions.
Reverse Power: Pickup and dropout setpoints are entered in
kilowatts or kVARs. The reverse power alarm occurs when the power
flows in a negative direction and remains at or below the negative
pickup value for the specified pickup delay (in seconds). The alarm
clears when the power reading remains above the dropout setpoint
for the specified dropout delay (in seconds).
Phase Reversal: Pickup and dropout setpoints and delays do not
apply to phase reversal. The phase reversal alarm occurs when the
phase voltage rotation differs from the default phase rotation. The
meter assumes that an ABC phase rotation is normal. If a CBA phase
rotation is normal, the user must change the meter's phase rotation
from ABC (default) to CBA. To change the phase rotation from the
display, from the main menu select Setup > Meter > Advanced. For
more information about changing the phase rotation setting of the
meter, refer to "Advanced Meter Setup Options" on page 26.
