Recommended Practice for Installation, Application, Operation, and Maintenance of Dry-Type Distribution and Power Transformers
This recommended practice describes general recommendations for the installation, application, operation, and maintenance of all single and polyphase ventilated, non-ventilated, and sealed dry-type distribution and power transformers or autotransformers, including those with solid-cast and/or resin encapsulated windings except transformers described as exceptions in IEEE Std C57.12.01. nnNOTE–Where IEEE standards do not exist for the transformers mentioned above or for other special transformers, this standard may be applicable as a whole or in parts subject to agreement between the parties responsible for the application and for the design of the transformer.
