Full load power W
W < 12 kW
Ⅰ.
12kW ≤ W < 120 kW
Ⅱ.
Ⅲ. 120kW ≤ W < 1200 kW
Ⅳ. 1200kW ≤ W < 12000 kW
Ⅴ.12000kW ≤ W < 120000 kW
*1 For calculating full load power W, refer to Table 4.2.1-1 (pages 4-5 to 4-7).
*2 Because the higher resolution than a typical watt-hour meter, the minimum digit values will change
more than 2 at once update. According to setting value of input voltage, primary current, primary
voltage of VT, secondary voltage of VT, primary current of CT and the condition of load.
