About this file
This image is a technical specification plate and schematic diagram for a Hyundai Auto Transformer (Model RP-8451), manufactured by Hyundai Heavy Industries Co., Ltd. in Ulsan, Korea.
The transformer is a single-phase unit rated at 60 Hz with a capacity of 366,667 kVA for HV and LV windings and 467,000 kVA for TV winding. It features multiple voltage taps on the high voltage side ranging from 551,250/3 to 498,750/3 volts, with corresponding amperage ratings for OA, FA, and FOA cooling modes. The low voltage side operates at 230,000/3 volts with amperage ratings of 1280, 1707, and 2134 amps respectively. The tertiary voltage side offers five tap positions ranging from 36,225.0 to 32,775.0 volts with amperage specifications listed for each configuration. The unit weighs approximately 505,400 pounds total, with component weights including untanking (262,600 lbs), tank and fittings (126,900 lbs), and insulating oil (129,100 lbs). The transformer includes bushing-type current transformers with various burden ratings and is designed for 100-hour vacuum filling. The schematic diagrams illustrate the bank connection configuration, vector diagram showing polarity as subtractive, and HV/LV/TV NLTC (no-load tap changer) circuit details.
