American National Standard Requirements for Pad-Mounted, Compartmental-Type, Self-Cooled, Single-Phase Distribution Transformers With High-Voltage Bushings: High Voltage (34 500 GrdY/19 920 V and Below) and Low Voltage (240/120 V, 167 kVA and Smaller)
New IEEE Standard - Inactive-Withdrawn.
This standard covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of single-phase, 60 Hz, mineral-oil-immersed, self-cooled, padmounted, compartmental-type distribution transformers with high-voltage bushings.
These transformers are rated 167 kVA and smaller, with high-voltages of 34500 GRD/19900 volts and below for operation between one phase and grounded neutral, and low-voltage of 240/120 volts.
These transformers are generally used for step-down purposes from an underground primary cable supply.
NOTE—Refer to the latest federal regulations concerning polychlorinated biphenyl (PCB) contaminations in transformers.
This standard is intended for use as a basis for determining performance, interchangeability, and safety of the equipment covered,
and to assist in the proper selection of such equipment.
