Manual 26086 EGCP-2 Engine Generator Control Package
Woodward 99
Alarms Affected
The generator current on A phase is monitored and used as an input for the
Overcurrent alarm. The EGCP-2 uses all three phase CT inputs for sensing
overcurrent conditions, and selects the phase with the highest current at any
given moment. Improperly calibrated B phase CT levels will affect the point of
Overcurrent detection on the generator.
The A Phase CT calibration has an affect on KW and KVAR levels for the B
phase, and for the sum of all three phases of the generator. The various alarm
setpoints which monitor real and reactive load levels are affected by this
calibration point.
CT Phase B Scale
Calibrates the B phase generator CT input.
Menus Affected
Changes in the calibration value will change the B phase current readout in both
the Generator Status menu. Changing this value will also have an effect on the
generator KW and KVAR levels.
Alarms Affected
The generator current on B phase is monitored and used as an input for the
Overcurrent alarm. The EGCP-2 uses all three phase CT inputs for sensing
overcurrent conditions, and selects the phase with the highest current at any
given moment. Improperly calibrated B phase CT levels will affect the point of
Overcurrent detection on the generator.
The B Phase CT calibration has an affect on KW and KVAR levels for the B
phase, and for the sum of all three phases of the generator. The various alarm
setpoints which monitor real and reactive load levels are affected by this
calibration point.
CT Phase C Offset
Calibrates the C phase generator CT input offset (zero current) reading.
Menus Affected
Changes in the calibration value will change the C phase current readout in the
Generator Status menu. Changing this value will also have an effect on the
generator KVA, KW, and KVAR levels.
Operations Affected
Generator Current is used in real and reactive load calculations. These
calculations are used in all real and reactive power control functions.
Alarms Affected
The generator current on C phase is monitored and used as an input for the
Overcurrent alarm. The EGCP-2 uses all three phase CT inputs for sensing
overcurrent conditions, and selects the phase with the highest current at any
given moment. Improperly calibrated A phase CT levels will affect the point of
Overcurrent detection on the generator.
