Q
Normalize Losses to Meter Base
Enter Value at Transformer Base for each quantity from calculations above. Enter Meter/Trf Factor
value from Base Conversion Factor calculations above. Calculate M/T Factor with Exponent by raising
the M/T Factor to the power indicated in the “Exp” (or Exponent) column.
Calculate the “Value at Meter Base” by multiplying the (M/T Factor w/ Exp) times the (Value at Trf
Base).
Q
Loss Watts Percentage Values
Meter Base kVA = 600 * (PT Multiplier) * (CT Multiplier) / 1000
= 600 * (____________) * (___________) / 1000
