The 2021 revision introduces several structural modifications designed to align high-voltage system architecture with modern safety expectations:

Organizations such as ANSI (USA), BSI (UK), DIN (Germany), or NSA (Australia) offer the document, often localized with national annexes or forewords.

❌ Using 2010 clearances for systems with arresters – 2021 reduces some gaps. ❌ Ignoring Annex B for soil resistivity modeling – leads to unsafe touch voltages. ❌ Applying AC rules to DC installations – that is IEC 61936-2. ❌ Overlooking fire separation between control buildings and HV equipment – clause 9.3 is strict.

Insulation coordination and minimum clearance distances (both in air and between barriers) were re-evaluated. The 2021 text provides clearer tables and formulas to calculate safe working zones, considering modern insulation materials and compact substation designs. 3. Updated Fire and Environmental Protection

. This third edition is the primary international standard for the design and erection of AC electrical power installations with nominal voltages exceeding Key Technical Updates in the 2021 Edition

The safety and reliability of high-voltage power systems are paramount for modern society. IEC 61936-1:2021 provides the "common rules" for the design and erection of electrical power installations, serving as the primary reference for engineers, utilities, and regulators. ❌ Applying AC rules to DC installations –

A is also available. It contains both the official standard and its commented version, providing a quick and easy way to compare all changes between edition 3.0 and the previous edition (2.1), with comments from IEC TC 99 experts explaining the reasons for the most relevant changes.

This standard does not dictate the design rules for overhead/underground lines running between distinct installations. It does not govern live-working procedures, mining machinery, fluorescent lighting, test labs, or medical X-ray environments. Prefabricated, type-tested switchgear components are also excluded, as they fall under standalone manufacturing standards like IEC 62271. Critical Technical Updates in the 2021 Edition

The 2021 revision introduced several significant technical shifts compared to the 2014 version: It does not govern live-working procedures

This version constitutes a technical revision that cancels and replaces the previous 2010 edition. Significant changes include: Clarified Scope

Control cables must be physically separated from power cables by a minimum of 0.3 meters or a metallic partition to prevent induced voltages.
