Understanding what the standard covers is as important as knowing its limitations. IEC 61936-1:2021 serves as the guiding link for a vast array of electrical assets commonly found in industrial plants, utility substations, and commercial buildings.
IEC 61936-1:2021 is the third edition of the "Power installations exceeding 1 kV AC and 1,5 kV DC - Part 1: AC" standard. Developed by the , this standard establishes the fundamental requirements for the design and erection of electrical power installations in systems with nominal voltages exceeding 1 kV AC and a nominal frequency up to and including 60 Hz. The primary goal of the standard is to guarantee the safety and proper functioning of these installations, protecting people, livestock, and property from the significant hazards associated with high-voltage electrical equipment.
