Modeling Harmonic Loads on Neutrals - Neher McGrath
Modeling Harmonic Loads on Neutrals - Neher McGrath
(OP)
Has anyone seen any research on how to properly model the heating affect of neutral current due to harmonics in Neher McGrath ductbank heat analysis? I have a data center project, where the load could have a good bit of harmonic distortion, and I've been modeling the neutral loads in ductbanks as just single phase power sources (with loads equal to 1.73 times the phase load for maximum harmonic distortion). Is the heating effect the same for currents induced by harmonics as it would be for 60Hz power? References would be greatly appreciated.
Thanks,
Andrew

Triplen harmonics in the neutral has been a big issue in the time of single-phase rectififers with capacitive DC-link.
Now a lot of standards make power-factor control mandatory for nearly every power electronics device connected single phase. A more smart approach is to use equpment with three-phase input where possible.
