This is a transformer nameplate/specification document from TRASFOR, a Swiss manufacturer located in Lugano. The transformer is a 3-phase, 1650 kVA unit manufactured in 2007 with reference number NO.00012 and serial number 08800549. The device operates at a rated frequency of 60 Hz and features a standard IEC 60076-11 ABS type design with model designation TNT 6HN 1M65/N.

The transformer has high voltage (HV) primary windings rated at 600V with secondary voltages of 1136.7V (U21) and 1190V (U22), delivering rated currents of 1587.7A (I1), 398A (I21), and 400.3A (I22) respectively. It utilizes an AN cooling system with H-H-H insulation class and AC 3/10/10 insulation level in kV. The unit has a maximum temperature rise of 115K above a 50°C ambient temperature, with a 7.00% rated impedance voltage. The transformer has a total mass of 4600 kg and operates at 100% loading time with an IP23/IP55 degree of protection for its enclosure and auxiliary boxes. Connection configurations are shown via terminal diagrams (1-4, 2-4, 2-5, 3-5, and 3-6) on the left side of the nameplate.
