    Abstract - (Show below) - (Hide below)

    Gives general requirements for the measurement of radio-frequency emissions emanating from measuring relays and protection equipment for power system protection. Includes control, monitoring and proc process interface equipment used with such systems. Based on CISPR 22. Defines the limits of acceptable conducted and radiated emissions and specifies test procedures. The object of the tests is to confirm that the equipment being tested will not cause conducted or radiated emissions above defined levels which might affect the satisfactory operation of other equipment. Any equipment or part of equipment which has the primary function of radio transmission and/or reception is excluded from this standard. Requirement defined are applicable to measuring relays and protection equipment in a new condition, all are type test onl
