System Wiring
3 Element Wye; 2.5 Element Wye; 2 CT Delta
Phases Displayed
A, AB, or ABC
NOTE:
Voltage Full Scale = PT Numerator x PT Multiplier
Example:
A 14400/120 PT would be entered as:
PT Numerator: 1440
PT Denominator: 120
Multiplier: 10
This example would display a 14.40kV.
Example CT Settings:
200/5 Amps: Set the Ct-n value for 200, Ct-Multiplier value for 1
800/5 Amps: Set the Ct-n value for 800, Ct-Multiplier value for 1
2,000/5 Amps: Set the Ct-n value for 2000, Ct-Multiplier value for 1
10,000/5 Amps: Set the Ct-n value for 1000, Ct-Multiplier value for 10
Example PT Settings:
277/277 Volts: Pt-n value is 277, Pt-d value is 277, Pt-Multiplier is 1
14,400/120 Volts: Pt-n value is 1440, Pt-d value is 120, Pt-Multiplier value is 10
138,000/69 Volts: Pt-n value is 1380, Pt-d value is 69, Pt-Multiplier value is 100
345,000/115 Volts: Pt-n value is 3450, Pt-d value is 115, Pt-Multiplier value is 100
