Good-morning,

I found this equation in Electrical Machines, Drives and Power Systems by Theodore Wildi (5th Edition)

Chapter 30 - Harmonics pg 800 (eq. 30.1) 

"Effective value of a distorted voltage"

V = Effective value of the distorted Voltage

Vf = Effective value of the fundamental

Vh = Effective value of all the harmonics

I hope this helps.
