scope:

This standard is intended as a basis for the establishment of performance, interchangeability, and safety requirements of equipment described, and for assistance in the proper selection of such equipment.

Electrical, mechanical, and safety requirements of ventilated, nonventilated, and sealed dry-type distribution and power transformers or autotransformers (single and polyphase, with a voltage of 601 V or higher in the highest voltage winding) are described.

The information in this standard applies to all dry-type transformers except as follows:

Instrument transformers;

Step- and induction-voltage regulators;

Arc-furnace transformers;

Rectifier transformers;

Specialty transformers;

Mine transformers.

When this standard is used on a mandatory basis, the word shall indicates mandatory requirements; the words should and may refer to matters that are recommended or permissive, but not mandatory.

NOTE - The introduction of this voluntary consensus standard describes the circumstances under which the standard may be used on a mandatory basis.
