Q
Scaling (CT, PT Ratios and System Wiring)
CT Numerator (Primary):
CT Denominator (Secondary):
CT Multiplier:
CT Fullscale:
Calculation Based on Selections
PT Numerator (Primary):
PT Denominator (Secondary):
PT Multiplier:
PT Fullscale:
Calculation Based on Selections
System Wiring:
Number of Phases: One, Two or Three
NOTE:
VOLTS FULL SCALE = PT Numerator x PT Multiplier
WARNING:
You must specify Primary and Secondary Voltage in Full Scale. Do not use ratios!
The PT Denominator should be the Secondary Voltage level.
Example:
A 14400/120 PT would be entered as:
PT Num: 1440
PT Denom: 120
Multiplier: 10
This example would display a 14.40kV.
Q
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.
Q
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-Multipier value is 100.
345,000/115 Volts: Pt-n value is 3470, Pt-d value is 115, Pt-Multiplier value is 100
345,000/69 Volts: Pt-n value is 345, Pt-d value is 69, Pt-Multiplier value is 1000.
