Definitions:

Phasor Rotation

The rotation of a phasor, which is a vector representing a sinusoidally varying quantity, in the complex plane, typically used in the analysis of AC circuits.

Fundamental Waveform

The basic frequency component of an alternating current or voltage, corresponding to the fundamental frequency of the system.

Pulsating Currents

A type of electrical current that varies in amplitude but not direction, often seen as the output of rectifiers and can be smoothed into a more constant DC current using filters.

Triplen Harmonic Frequencies

Odd multiples of the third harmonic frequency that, when present in three-phase electrical systems, can lead to neutral conductor current overload and equipment overheating.
