Power System Utilization
Loss Load Factor
LLF = 0.3 \times LF + 0.7 \times LF^2
Variables
| LLF | Loss load factor | - |
| LF | Load factor (as a fraction) | - |
Engineering Example
At LF = 0.65: LLF = 0.3×0.65 + 0.7×0.65² ≈ 0.490.
Practical Site Example
A standard approximation used to estimate I²R energy losses on a feeder from its load factor alone.
