GE Multilin B30 Bus Differential System 6-136 ACTUAL VALUES 6.3 METERING66.3.2 BUS ZONEPATH: ACTUAL VALUES METERING BUS BUS ZONE 1These values display the differential and restraint currents phasors for the bus zone. The magnitudes are displayed in pri-mary amperes (see chapter 8: Theory of operation for additional details).6.3.3 SOURCESa) MAIN MENUPATH: ACTUAL VALUES METERING SOURCE SRC1This menu displays the metered values available for each source.Metered values presented for each source depend on the phase and auxiliary VTs and phase and ground CTs assignmentsfor this particular source. For example, if no phase VT is assigned to this source, then any voltage, energy, and power val-ues will be unavailable.
