systems in the voltage range 72,5 kV to 800 kV - A method of calculation - IEC 61472:2004Describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV 2019-04-02 The word is actually an acronym that stands for minimum approach distance, which is the calculated safe working distance that provides worker protection when working on or in the vicinity of energized lines and equipment. As with other articles in this series, we must begin with the hazard. The minimum approach distance shall include an “adder” to compensate for the inadvertent movement of the worker relative to an energized part or the movement of the part relative to the worker. This “adder” shall account for this possible inadvertent movement and provide the worker with a comfortable and safe zone in which to work. If you select the minimum detectable object size of 150 mm 5.91", “H” (the height of the detection plane) exceeds 1000 mm 39.37".

2021-04-13 Let’s kick off this article with a definition of what “MAD” means in the utility sector – and it does not mean that we’re upset with you. The word is actually an acronym that stands for minimum approach distance, which is the calculated safe working distance that provides worker protection when working on or in the vicinity of energized lines and e This means minimum approach distances will need to be increased accordingly.

These diagrams provide quick guidance and reference on minimum approach distances for 220 kV and 110 kV structures.
