The Effect Of Power Transformers
Feb 11, 2026
Compared to the new S9 type distribution transformer, the three-phase amorphous alloy core distribution transformer offers considerable annual energy savings.
Taking an 800kVA transformer as an example, with ΔP0 of 1.05kW, and considering that both types of distribution transformers have the same load loss (ΔPk=0), the annual energy saving per unit can be calculated as:
ΔWs=8760(1.05+0.62×0)=9198kWh
This calculation demonstrates the exceptional energy-saving performance of the three-phase amorphous alloy core distribution transformer series. Furthermore, the fully sealed tank design prevents the transformer oil from contacting the outside air, thus preventing oil oxidation, extending the product's lifespan, and saving users maintenance costs.
