5-25

— K-factor Product overview

Features • Full-width copper electrostatic shielding standard • Unique core and coil design using grain-oriented silicon steel • Core and coil assemblies mounted

K-factor is a standardized way to indicate the ability of a transformer to withstand harmonics. These units shall not exceed rated winding temperature rise at full load and rated K-factor. Neutrals and lugs are capable of handling 200% of rated secondary full load current. Full-width copper electrostatic shielding is standard on all ABB K-factor rated transformers. Effective coupling capacitance is 30 pf. Common mode noise attenuation averages up to 120 dB, and transverse mode noise attenuation averages up to 30 dB.
