CHAPTER 6: USING THE METER GE COMMUNICATOR PROGRAMMING OVERVIEW
EPM 2200 POWER METER – INSTRUCTION MANUAL 6–21
• CT Numerator (Primary): 1-9999
• CT Denominator (Secondary): 1 or 5 (factory set)
• CT Multiplier: 1, 10, or 100
• CT Fullscale: Calculation Based on Selections (click Recalculate to view)
• PT Numerator (Primary): 1-9999
• PT Denominator (Secondary): 40-600
• PT Multiplier: 1, 10, 100, or 1000
• PT Fullscale: Calculation Based on Selections (click Recalculate to view)
• System Wiring: 3 Element Wye; 2.5 Element Wye; 2 CT Delta
• Phases Displayed: A, AB, or ABC
Note
VOLTS FULL SCALE = PT Numerator x PT Multiplier
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.
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-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.
Note
Settings are the same for Wye and Delta configurations.
ENERGY AND DISPLAY
The settings on this screen determine the display configuration of the meter
faceplate.
