EN 61000-6-5 specifies the general requirements for the immunity of electrical and electronic equipment intended to be used in power station and substation environments. This standard aims to ensure that such equipment can operate correctly under the electromagnetic conditions typically found in these environments. It includes criteria for testing and performance for a range of electromagnetic disturbances, such as electrostatic discharge (ESD), radiated and conducted radio-frequency (RF) electromagnetic fields, electrical fast transients/bursts, surges, conducted disturbances induced by RF fields, and voltage dips, interruptions, and variations. The goal is to provide a high level of immunity to electromagnetic disturbances, ensuring reliable operation and safety.
