About this file
This document is an Attachment Brand Name or Equal Specifications for a 150 KVA 3-Phase Transformer, solicitation number 140R2025Q0088. The specifications detail a liquid-filled, pole-mounted transformer with a Larson/MT-UPM-R7-3P-DMP-150KVA-YT-CP-A6-BM-CZ-2ZZ-M1 equivalent part number. Key technical requirements include three-phase configuration, 13800V primary voltage, 208Y/120V secondary voltage, delta and wye-n windings, 150 KVA power capacity, and 60 Hz frequency. The transformer features a 5-position tap changer, copper windings, mineral oil insulation, stainless steel hardware, and a weatherproof epoxy coating.
The transformer meets multiple compliance standards, including DOE 2016 Efficiency Ratings and various ANSI/IEEE specifications (C57.12.00 through C57.12.80). It achieves 99.00% efficiency when operating at 50% of nameplate base kVA. Factory testing includes comprehensive evaluations such as winding resistance, insulation resistance, voltage ratio error, short-circuit impedance, no-load and load loss tests, induced voltage withstand, pressure integrity, polarity, and excitation current tests. The unit includes external labeling with KVA rating, a non-PCB label, and a stainless steel riveted nameplate.
