About This Item
IEC 61472-2:2021 provides a technical reference for determining the electrical component distance used in live working on AC systems from 1,0 kV to 72,5 kV. It is relevant where organizations need a documented basis for approach-distance calculations, risk management, and operational control during energized work. By defining a method tied to the electrical component distance, the document supports engineering review, technical validation, and compliance workflows for work on medium-voltage AC installations.
Purpose of IEC 61472-2:2021
The purpose of IEC 61472-2:2021 is to support the determination of minimum approach distances by focusing on the electrical component distance for AC systems within the stated voltage range. In practical terms, it helps engineers and safety teams evaluate how proximity limits are established for live working conditions. The standard is particularly useful when preparing technical documentation, performing documented evaluation, or aligning internal procedures with a consistent basis for approach-distance assessment.
Compliance applications of IEC 61472-2:2021
IEC 61472-2:2021 is commonly used in compliance preparation, work planning, and technical assessment for energized electrical equipment and AC distribution systems. It may be referenced during internal verification activities, method selection, or laboratory evaluation where approach-distance criteria need to be justified. Procurement teams and compliance specialists can also use it as a supporting technical document when reviewing procedures, contractor requirements, or safety documentation for live working operations.
Benefits of IEC 61472-2:2021
Using IEC 61472-2:2021 can improve consistency in safety decisions, engineering documentation, and conformity assessment preparation. It offers a structured basis for determining minimum approach distances, which may help reduce operational risk and support clearer procedure control across maintenance and utility workflows. For organizations managing technical compliance, it can strengthen review processes, improve alignment between planning and execution, and provide a reliable reference for quality assurance and technical validation.
