A6220 Shaft vibration measurement module

Menus Affected Changes in the calibration value will change the B phase current readout in the Generator Status screen. 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 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 effect on kW and kVAR levels for the B phase, and for the sum of all three phases of the generator. The various alarm set points that 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 screen. Changing this value will also have an effect on the generator kW and kVAR levels.
