PC57.12.01 - Standard for General Requirements for Dry-Type Distribution and Power Transformers
This standard describes electrical, mechanical, and safety requirements of single and polyphase ventilated, non-ventilated, and sealed dry-type distribution and power transformers or autotransformers, with a voltage of 601 V or higher in the highest voltage winding. This standard applies to all dry-type transformers, including those with solid-cast and/or resin encapsulated windings except as follows: a) Instrument transformers b) Step- and induction-voltage regulators c) Arc-furnace transformers d) Rectifier transformers e)Specialty and general-purpose transformers f) Mine transformers g) Testing transformers h) Welding transformers
