本标准规定了用于保护和控制电力设备的继电器、继电器系统和控制装置的设计试验，这些设备与辐射电磁场的抗扰度有关。对于具有通信端口的设备，如果设备不执行保护或控制功能，则通信功能的测试包含在IEEE Std.1613中。当设备执行保护或控制功能并具有通信端口时，IEEE C37.90标准系列涵盖了所有通信功能的测试。

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.
