STEP 0: Pre-Calculation Summary

Formula Used

Utilisation Factor of Transformer Core = Net Cross Sectional Area/Total Cross Sectional Area
UF = A_net/A_total
This formula uses 3 Variables

Variables Used

Utilisation Factor of Transformer Core - Utilisation Factor of Transformer Core is defined as the ratio of dc power output to the transformer Volt-Ampere (VA) rating required by the secondary winding.
Net Cross Sectional Area - (Measured in Square Meter) - Net Cross Sectional Area is to be determined from the gross cross section area minus all openings and holes for fasteners.
Total Cross Sectional Area - (Measured in Square Meter) - Total Cross Sectional Area is the sum of all the partial cross-sections.

STEP 1: Convert Input(s) to Base Unit

Net Cross Sectional Area: 1000 Square Centimeter --> 0.1 Square Meter (Check conversion here)
Total Cross Sectional Area: 3100 Square Centimeter --> 0.31 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

UF = A_net/A_total --> 0.1/0.31

Evaluating ... ...
