IEC 61936-1:2021 sets uniform safety and reliability requirements for AC systems over 1 kV and up to 60 Hz. It covers installations in substations, power stations, industrial sites, and offshore facilities, while excluding overhead/underground lines, mining, and specific switchgears. The 2021 update brings crucial revisions: IEC 61936-1:2021
