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 Options setup in PAS.
3
The default Current scale is 2  CT secondary current (2.0A with 1A secondaries, 10.A with 5A secondaries). You can
change it via the Device Options setup in PAS.

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.
