IEEE Std C57.12.34-2004
IEEE Standard Requirements for Pad-Mounted, Compartmental-Type, Self-Cooled, Three-Phase Distribution Transformers, 2500 kVA and Smaller-High Voltage: 34 500 GrdY/19 920 Volts and Below; Low Voltage: 480 Volts and Below
Certain electrical, dimensional, and mechanical characteristics are set forth as well as certain safety features of three-phase, 60 Hz, mineral-oil-immersed, self-cooled, pad-mounted, compartmental-type distribution transformers. These transformers are rated 2500 kVA and smaller, with high-voltages of 34 500 GrdY / 19 920 volts and below, and with low-voltages of 480 volts and below. This standard covers the connector, bushing and terminal arrangements for radial or loop feed systems. This standard does not cover the electrical and mechanical requirements of any accessory devices that may be supplied with the transformer.
