Overload capacity: 1000 % of rating for 3 sec., 200 % for 10
sec., 120% continuous
CONFIGURATION
1: 3-phase / 3-wire
■ How To Determine Var Range
Calibration Range [var] = (Measuring Range) ÷
((VT Ratio) × (CT Ratio))
[1] INPUT (unbalanced load)
(Voltage must be balanced.)
1: 110 V / 5 A AC
Check that the required calibration range is within the
available range in the table.
2: 110 V / 1 A AC
[example]
3: 220 V / 1 A AC
3-phase / 3-wire, measuring range 75 kvar,
VT 220 / 110 V, CT 250 / 5 A
4: 220 V / 5 A AC
(75 × 10 [var])÷((220 / 110) × (250 / 5))= 750 [var]
