When paralleling generators of different pitch 3rd harmonic current will flow in the ground wire causing the ground fault shunt-trip breaker.
The transformers included in HL TransMax product are premium transformers featuring:
Blockade Technology prevents third harmonics currents from:
With Blockade Technology, transformers do not need to be K-rated and oversized or doubled neutrals are not required.
Premium non-K-rated transformers used in TransMax products feature a 4% - 6% impedance.
Equivalent k-Rated transformers of the same kVA, by the nature of their design, typically have a lower impedance. This lower impedance results in slightly HIGHER harmonic currents throughout the system, causing higher harmonic heat losses, decreased useable capacity, increased neutral-to-ground voltage, and increased energy usage.
K-rated transformers do not mitigate harmonic currents. They are simply designed to withstand the heat produced by these extra currents and to not fail when subjected to harmonic overheating.
The HL TransMax products, using standard impedance transformers with Blockade Technology provide:
Blockade Technology benefits, matched by no other harmonic mitigating product, include:
