Definitions:

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.

Phase Currents

Phase currents refer to the currents that flow through each phase of a multi-phase system, such as in three-phase electrical systems, highlighting their individual magnitudes and directions.
