TRANSFORMERS COMMITTEE

Dielectric Tests Subcommittee

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.
