Revision of IEEE Std C37.90.2-1995. Design tests for relay and relay systems that relate to the immunity of this equipment to Radiated Electromagnetic Interference from Transceivers are specified. Field strength, test frequencies, modulation, sweep rates, equipment setup and connection, test procedures, criteria for acceptance, and documentation for test results are described. This standards has been harmonized with IEC standards where consensus could be reached.

Standard for Relays, Relay Systems, and Control Devices used for Protection and Control of Electric Power Apparatus u2013 Radiated Electromagnetic Interference Withstand Capability Requirements and Tests
This standard specifies 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 radiated electromagnetic fields. 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 the IEEE C37.90 family of standards.
