Two types of design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients are specified. Test generator characteristics, test waveforms, selection of equipment terminals on which tests are to be conducted, test procedures, criteria for acceptance and documentation of test results are described. This standard has been harmonized with IEC standards where consensus could be reached.

C37.90.1-2024
IEEE Draft Standard for Relays, Relay Systems, and Control Devices used for Protection and Control of Electric Power Apparatus-Surge Withstand Capability (SWC) and Electrical Fast Transient (EFT) Requirements and Tests
This standard specifies 1 design tests for relays, relay systems, and control devices used for Protection and Control of Electric Power Apparatus, that relate to the immunity of this equipment to repetitive electrical transients. Two types of tests are specified, the slow damped oscillatory test, and the electrical fast transient (EFT) burst test. For devices with communication ports, where the device does not perform protection or control functions, testing of the communication functions is covered by IEEE Std. 1613. Where the device performs protection or control functions and has communication ports, tests for all communication functions are covered by this document. For devices without communication ports, the tests are covered by this document.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
