DIELECTRIC TEST 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.
