“VT” is VT ratio setting of distance protection, and “VTs1” is VT ratio setting of a reference
voltage input for voltage and synchronism check element as shown in Figure 2.6.3.1.
In a voltage setting, set “SY1UV”, “SY1OV”, “OVB”, “UVB”, “OVL1” and “UVL1” based on
the VT rating for voltage and synchronism check. (When a voltage rating between line VT and
busbar VT is different as shown in Figure 2.6.3.1, the voltage input from “VT” is matched to the
rating of “VTs1” using the setting of “VT” and “VTs1”.)
