Products
Hybrid Transformer
harmonic attenuation, and unbalanced improvement. It represents a pioneering
technology developed through collaborative research and development with five power
generation companies under KEPCO.
Why Hybrid?
Harmonic attenuation transformer
The “Transformer + harmonic attenuation + unbalanced improvement” function offers a three-in-one solution, reducing investment and maintenance costs by eliminating the need for separate harmonic filters.
Industry-first development and commercialization
Developed through collaborative research with 5 power generation companies under KEPCO, our product is an industry-first and has been supplied to over 700 major institutions.
Expected Effects
reducing LCC(Life Cycle Cost) costs by 15~20% compared to conventional transformers.
