Abstract:The standards of the IEC 61000-4-X,the IEC 60255-X and the GB/T 14598 are discussed in this paper. Protective relay works in the serious electromagnetic environment of the substations in which there are electrostatic discharge, electrical fast transient/burst, 1MHz oscillatory waves and surge disturbances. The bay-oriented design techniques have been widely adopted in power systems. The microprocessor based protective relay is more susceptible and frangible to electromagnetic compatibility. The mechanism of electrical fast transient/burst is introduced in this paper. According to each port of the numerical protection, Some measures aimed at these transient disturbances are presented too.
Keywords:electrostatic discharge  electrical fast transient/burst  1MHz oscillatory waves  surge  port
