Metered bus parameters include the voltage across phases A and B (Vab), phases B and C (Vbc),
phases A and C (Vca), and the average bus voltage. The frequency of the bus voltage is also metered.
Primary- and per-unit values are available. Figure 13-5 illustrates the bus primary-values metering screen.
