What is the triplen harmonic associated with odd multipliers?

The triplen harmonic is specifically associated with the third harmonic, which results from the presence of odd multiples of the fundamental frequency. In three-phase systems, the third harmonic is particularly significant because it tends to add up in the neutral conductor, potentially leading to increased current and other issues.

When harmonics are generated, they are multiples of the fundamental frequency, and the third harmonic represents one of the first odd multiples (3 x fundamental frequency). This harmonic is unique because it is a multiple of three, and in three-phase systems, it can create problems like neutral overload. Other odd harmonics such as the fifth and seventh are also present, but they do not specifically combine like the third harmonic does in these systems.

Thus, the third harmonic is the one that represents the triplen harmonic related to odd multipliers.
