GE DS3800HCMA1E1G通讯控制板
Van、Vbn、Vcn、VOLTAGE：显示与A、B和C电压输入相对应的各相电压。只有当VT RATIO、VT NOMINAL SECONDARY和voltage WILING（电压接线）设定值与安装的VT匹配时，才能正确测量该电压。如果显示的电压与实际电压不匹配，检查设定点和接线。仅当VT接线配置为Y形输入时，才会显示此信息。IVG/Vavg：显示三相电流/电压的平均值。如果VT接线设置点设置为单相直接，则该值不可见。当VT接线设置为4线Y字形（3个VT）、4线Y形直接、4线W字形（2个VT）或3线直接时，显示L-N，当VT接线设为3线三角形（2个VTs）时，显示L。Vab、Vbc、Vca、VOLTAGE（电压）：显示与A、B和C电压输入相对应的每条线路电压。只有当VT RATIO、VT NOMINAL SECONDARY和voltage WILING（电压接线）设定值与安装的VT匹配时，测量的电压才正确
Van, Vbn, Vcn, VOLTAGE: Displays each phase voltage corresponding to the A, B, and C voltage inputs. This voltage will be measured correctly only if the VT RATIO, VT NOMINAL SECONDARY, and VOLTAGE WIRING setpoint values match the installed VTs. If the displayed voltage does not match the actual voltage, check the setpoints and wiring. This message appears only if the VT WIRING is configured for a wye input.Iavg/Vavg: Displays the average of the three phase currents/voltages. This value is not visible if the VT WIRING setpoint is set to SINGLE PHASE DIRECT. L-N is displayed when VT WIRING is set to 4 WIRE WYE (3 VTs), 4 WIRE WYE DIRECT, 4 WIRE WYE (2 VTs), or 3 WIRE DIRECT and L-L is displayed when VT WIRING is set to 3 WIRE DELTA (2 VTs). Vab, Vbc, Vca, VOLTAGE: Displays each line voltage corresponding to the A, B, and C voltage inputs. The measured voltage is correct only if the VT RATIO, VT NOMINAL SECONDARY, and VOLTAGE WIRING setpoints match the installed VTs
