What is True RMS? And Why is it Important in a Phase Monitor?

Monday: April 14, 2014 : Three-Phase Monitor Relays

RMS stands for Root Mean Square. True RMS is a mathematical formula that is used to calculate the effective value of an AC wave shape. To understand why this is important, it is helpful to first discuss what a phase monitor does. A phase monitor measures voltage to confirm the presence of a desired voltage; it
