This standard applies to measuring relays and protective devices used for power system protection, including control, monitoring and process interface equipment used with these devices. This standard specifies the electromagnetic compatibility requirements for measuring relays and protective devices. For devices not consisting of electrical and electronic components, such as electromechanical relays, the tests specified in this standard are not required. The requirements of this standard apply to new measuring relays and protective devices. All tests specified are type tests only.
