Section 3 NAME AND FUNCTION OF EACH PART
(3) Resolution of measured data
Resolution of measured data according to the rating (phase wire system, primary voltage setting, and
primary current setting) is described as follows.
(a) Current, current demand
Primary current setting
PA
*1
PA < 40 A
40 A ≤ PA < 400 A
400 A ≤ PA < 4000 A
4000 A ≤ PA
*1: Case of setting value of the primary current (Un\G2) is "0", the primary current (PA) is value of
primary current of CT (Un\G7).
In other cases, the primary current (PA) is the value of primary current (Un\G2).
*2: Digits lower than the resolution are fixed to 0.
(b) Voltage
Primary voltage setting
PV *1
PV < 330 V
330 V ≤ PV < 3300 V
3300 V ≤ PV
*1: Case of setting value of the primary voltage (Un\G1) is "0", the primary voltage (PV) is value of
primary voltage of VT (Un\G5).
In other cases, the primary voltage (PV) is the value of primary voltage (Un\G1).
*2: Digits lower than the resolution are fixed to 0.
(c) Electric power, electric power demand, Reactive power, Apparent power
Full load power W
I
II 12 kW ≤ W < 120 kW
III 120 kW ≤ W < 1200 kW
IV 1200 kW ≤ W < 12000 kW
V 12000 kW ≤ W < 120000 kW
*1: Full load power (W) can be calculated by the following formula.
For calculating full load power W, refer to "Table 3.4.1-3 How to calculate full load power".
Full load power W(kW) = α × Primary voltage (V) × Primary current (A) / 1000
Case of single-phase 2-wire: α = 1
Case of three-phase 3-wire: α = √ 3
Case of single-phase 3-wire: α = 2
*2: Digits lower than the resolution are fixed to 0.
*3: The module is kvar for reactive power and kVA for apparent power.
