DRY TYPE TRANSFORMERS SUBCOMMITTEE

SCOPE

Study and review engineering aspects of those transformers and reactors in which a significant component of the internal insulation is air or other insulating gas;
Develop and maintain related standards, recommended practices and guides for such products;
Coordinate with other technical committees, groups, societies and associations as required.
