Data Units
PT Ratio = 1 0.1V U1
PT Ratio > 1 1V
U2 0.01A
PT Ratio = 1 1W/Var/VA U3
PT Ratio > 1 1kW/kvar/kVA
1
CT Ratio = CT primary current/CT secondary current
2
The default Voltage scale is 144V (120V +20%) unless you changed it in your device through the Device Data Scale setup
registers (see Section 3.1) or via the supplemental PAS software.
3
The default Current scale is 2 × CT secondary current (1A or 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.
