Data Units
PT Ratio = 1 0.1 V U1
PT Ratio > 1 1 V
U2 0.01 A
PT Ratio = 1 0.001 kW/kvar/kVA U3
PT Ratio > 1 1 kW/kvar/kVA
1
CT Ratio = CT primary current/CT secondary current
2
The default Voltage scale is 144V (120V +20%). You can change it via the Device Data Scale setup (see Section 3.1) or via
the Device Options setup in PAS.
3
The default Current scale is 2 × CT secondary current (2 × 1A or 2 × 5A depending on the order).
4
Pmax is rounded to whole kilowatts. With PT=1.0, if Pmax is greater than 9,999,000 W, it is truncated to 9,999,000 W.
