Revision Standard - Superseded. Superseded by IEEE C37.90.1-2002. Design tests intended for protective relays and relay systems, including those incorporating digital processors, are specified. The tests are intended to be applied to a complete relay system under simulated operating conditions. Oscillatory and fast transient test-wave shapes and characteristics are defined. The equipment to be tested and the test conditions are described, and the points of application of the test wave are shown. Acceptance is defined, and the requisite test data are specified.
These SWC tests are design tests intended for protective relays and relay systems, including those incorporating digital processors. The application of SWC tests to equipment other than protective relays and relay systems is the responsibility of those specifying the testing. The oscillatory and fast transient SWC tests are presented as distinct tests in the following section. However, it is not intended to prohibit a combined test, provided all requirements of the individual SWC tests are met.
