Anotation

Revision Standard - Active.
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 are specified in this standard. 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.
