Performance Characteristics Subcommittee Scope

• Study and review the treatment of loss, impedance, exciting current, inrush current and other performance characteristics and their methods of application, measurement or test 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.
