IEEE C37.90.2:2004 (R2010)

Revision Standard - Inactive-Reserved.
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.

The scope of this project is to establish a test method for evaluating the susceptibility of protective relays to single-frequency electromagnetic fields in the radio frequency domain, such as those generated by portable or mobile radio transceivers.
The purpose of this standard is to provide a common reference and test procedure that industry can use for evaluating the performance of static protective and control relays used in electric power facilities.
