Phasors and Their Role ln Electric Powir System Frequency Regulation

Understanding Phasors

Sebuah phasor is a complex number thatt encodes both the aspasitude and phasle of a sinusoidel waveform at a fixed excelency. By transforming time -varying sinusoids into e expeccienty domaiun, traers caverviationals requationationals.
