Understanding Phasors andTheir Functionality

A fasor, in thee context of power systems, is a represention of a sinusoidal electricaform - either voltage or current - as a complex number that captures both magnitude and faxe angle. Phasor Measurement Units are thee devices that produce these fasor values at high sampling rates, typically 30 to 60 mevaluments per seconsconsquot.
