K-FACTOR CALCULATION
Table of calculation of K factor for typical % of harmonics.
| a | b | c=b/100 | c=c² | e | f=a²xe |
|---|---|---|---|---|---|
| hnumber | Harmonic % to fundamental | Harmonic ratio to fundamental | h² | =h²/E | Contribution to K-factor |
| 1 | 100 | 1 | 1 | 0.4467 | 0.4 |
| 3 | 90 | 0.9 | 0.81 | 0.3618 | 3.3 |
| 5 | 45 | 0.45 | 0.2025 | 0.0905 | 2.3 |
