Synchronization

Slip Frequency, Slip Angle, and Voltage Difference are metered.

Synchronization metering data is found in BESTCOMSPlus (Figure 127) and on the Metering > Analog

Metering > Synchronization screen of the front-panel display.

Differential

The differential value is calculated as shown in the following equations:

If 87 Mode = Phase Differential and Slope Mode = Maximum, then IOP A =
