Overview: The document provides detailed information on SolaHD K-Factor transformers, designed to handle harmonic currents from non-linear loads without overheating. These transformers are rated K-4, K-13, and K-20, indicating their capacity to manage harmonic content while maintaining temperature limits.

Specifications: The transformers feature conductors that can carry harmonic currents without exceeding insulation temperature ratings. They are UL 1561 listed up to K-20 and have a rated temperature rise of 150°C with 220°C insulation. The design accounts for stray losses and manages DC flux caused by triplen harmonics.

Features: Key features include shielded power quality, a core and coil design to manage zero sequence flux, and the ability to provide 100% rated current without overheating or core saturation.

Typical Load K-Factors: The document lists typical load K-Factors for various equipment, such as electric discharge lighting (K-4), telecommunications equipment (K-13), and mainframe computer loads (K-20).

Accessories and Optional Designs: Options include wall mounting brackets, weather shields, non-ventilated designs, low temperature rise units, open core and coil designs, copper wound designs, and alternate voltages. Not all designs are UL listed.

Selection Tables: Detailed tables provide specifications for three-phase transformers with different K-Factor ratings, including dimensions, weight, and electrical connections for primary and secondary voltages.

Electrical Connections: The document includes diagrams and instructions for connecting primary and secondary voltages for various transformer series, such as ES14, ES12, and ET series.
