In IEEE 519-2022 the telephone influence factor of a voltage or current wave is the ratio of the root of the sum of the squares of the weighted rms values of all its sine wave components, fundamental and harmonics, to the unweighted rms of the whole wave, with a weighting that combines C-message weighting and a term proportional to frequency.
