Definitions:

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.

Neutral Conductor

A conductor that carries only the imbalance of current between the live conductors in a multiphase system, and is at ground potential.

Negative-Sequence Harmonic

Causes the rotating magnetic field of a polyphase motor to rotate in a direction opposite that of the fundamental frequency.
