Synchronization
Slip Frequency, Slip Angle, and Voltage Difference are metered.
Synchronization metering data is found in BESTCOMSPlus (Figure 133) 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 = | ���� |
