The standard, "Power installations exceeding 1 kV AC and 1,5 kV DC – Part 1: AC," sets international requirements for designing and installing high-voltage AC systems, covering power stations, substations, and equipment like transformers and cables. This third edition, issued in July 2021, replaces the 2010 version to improve safety and operational standards. It generally applies to systems exceeding 1 kV at 50/60 Hz, excluding specialized areas like electrified railways or mining. Key Changes and Content (2021 Edition)
Because the IEC works closely with the International Organization for Standardization, the ISO Store also hosts authorized copies of joint and complementary standards.

includes rotating electrical machines, switchgear, transformers and reactors, converters, cables, wiring systems, batteries, capacitors, earthing systems, buildings and fences (that are part of a closed electrical operating area), associated protection, control and auxiliary systems, and large air core reactors.
The IEC 61936-1:2021 standard is the definitive international benchmark for designing and installing power installations exceeding 1 kV AC. This updated version replaces the 2010 edition, introducing critical safety refinements and technical modernizations essential for high-voltage engineering. The standard, "Power installations exceeding 1 kV AC
The most likely explanation is a typographical or formatting error in the keyword. The numeric string "61936" points directly to a well-known standard, while "12021" does not correspond to any valid year (2021) or part number for that series.
is the definitive international standard governing the design, erection, and verification of high-voltage AC power installations exceeding 1 kV AC and nominal frequencies up to 60 Hz . Published by the International Electrotechnical Commission, this third edition provides foundational safety rules to protect people, livestock, and property while guaranteeing the proper functional operation of electrical infrastructure. Key Changes and Content (2021 Edition) Because the
The scope also on electrical power installations and is not intended to cover low-voltage installations up to 1 kV, which fall under IEC 60364 (all parts).
All switchgear assemblies must withstand internal arc faults for at least 0.5 seconds. The standard references for classification (IAC – Internal Arc Classified).
