Guides for operation of transformers, regulators, and reactors: AIEE transformer subcommittee: Guide for loading oil-immersed distribution and power transformers

THIS guide covers general recommendations for loading all types of oil-immersed transformers with class-A insulation except water-cooled transformers built before 1929, self-cooled transformers rated at 200 kva or less, and transformers having a rated full-load current less than ten amperes. They include transformers immersed in synthetic or noninflammable liquids.
