46、ntroduction This introduction is not part of IEEE Std C57.12.34-2015, IEEE Standard Requirements for Pad-Mounted, Compartmental-Type, Self-Cooled, Three-Phase Distribution Transformers, 10 MVA and Smaller; High-Voltage, 34.5 kV Nominal System Voltage and Below; Low-Voltage, 15 kV Nominal System Volt

47、age and Below. This standard was first published in 2004, and was a revision and combination ANSI Std C57.12.22-1993 American National Standard for TransformersPad-Mounted, Compartmental-Type, Self-Cooled Three-Phase Distribution Transformers with High-Voltage Bushings, 2500 kVA and Smaller: High Vo

48、ltage, 34 500 Grd Y/19 920 Volts and Below; Low Voltage, 480 Volts and BelowRequirements; and IEEE Std C57.12.26-1992 IEEE Standard for Pad-Mounted, Compartmental-Type, Self-Cooled, Three-Phase Distribution Transformers for Use with Separable Insulated High-Voltage Connectors (34 500 Grd Y/19 920 V

49、and Below; 2500 kVA and Smaller). This resulted in a single standard that brought together pad-mounted transformers with either high-voltage bushing or separable connectors. In 2009, the standard was revised and two significant changes to the scope were made. First, the size of units were increased to 5 MVA, and second the low-voltage rating was changed from 480 V and below to 15 kV and below. This facilitated the development of standard requirements for pad-mounted transformers that could be used for step-down as well as distribution service and required substantial updat
