RMS is Root Mean Squared. If you have a sinewave baseline Peak value of 1, your Peak to Peak (P-P) is 2. Then your Average value of 0.637 and finally an RMS value of 0.707. P-P is the value of the energy that is doing work. It inherently is void of transients/harmonics distortion. If you use a multimeter that measures in true RMS, it will have greater accuracy than that of an average reading meter, and usually cost more money. I've posted the ratios of the various units, to explain how to calculate it would take more time and space.

1> what r different types of fault in cables? How will u locate and test these faults? 2> why earth wire is provided on top throughout the transmission line. why not only on towers? How much area it can protect? 3> what r different types of transmission losses? How power loss can be minimized? 4> what is the % of power loss on transmission lines?
