Key performance highlights

• Exceptional insulation integrity: Extensive testing shows extremely high insulation resistance between windings and ground as well as between primary and secondary circuits, demonstrating outstanding dielectric reliability and long-term protection against moisture and contamination.
• Strong withstand capability: The transformer passed high-voltage withstand and induced-overvoltage tests with clear margins, indicating robust tolerance to transient stresses and good protection against surges or switching events.
• Low no-load and load losses: Measured losses on both no-load and loaded conditions are controlled and predictable, contributing to higher operational efficiency and lower heat generation in service — beneficial for lifecycle operating costs and cooler, more reliable installations.
• Tight impedance and voltage behavior: The transformer exhibits stable impedance and tight voltage regulation under load, ensuring consistent voltage delivery to downstream equipment and minimizing disruption to sensitive loads.
• Solid mechanical and grounding design: Grounding hardware and grounding resistance meet rigorous criteria, giving installers confidence in safety and effective fault clearing.
