Dielectric Tests Subcommittee Scope

• Study and review engineering aspects of test voltage requirements for service conditions, or conversely, voltage tests that will determine that service requirements are met for liquid filled transformers and reactors.

• Develop and maintain related standards, recommended practices and guides for such criteria.

• Coordinate with other technical committees, groups, societies and associations as required.
