Synchroscope
When the optional synchronism-check function is added to the SEL-700G, the
synchroscope is available in QuickSet. This option displays a graphical phasor
representation of the difference between the bus (voltage and frequency) and
the generator (voltage and frequency).
Start the autosynchronizer from the HMI screen by clicking the Start button.
This commands the SEL-700G to begin the synchronism process. Throughout
the process, you can see the phasor difference between the bus and the
generator. Figure 3.16 shows an example of the SEL-700G synchroscope.
