Revision Standard – Inactive – Superseded. 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 wave-forms, 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. An errata is available at http://standards.ieee.org/reading/ieee/updates/errata/C37.90.1-2002_errata2.pdf
