After 10 years and as many drafts, proposed IEC standard 61472 is now in the final voting stage. The standard, when published, will define the IEC method of calculating minimum approach distances (MAD) for live working for use world-wide. The standard 61472 provides a method of calculating MAD for voltages between 1 kV and 800 kV AC. To obtain the minimum approach distance required, it is first necessary to determine the maximum electrical stress (transient overvoltage-TOV) that can reach the work site and then to determine the minimum distance that must be maintained to withstand that electrical stress. IEC 61472:2013 describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV. This standard addresses system overvoltages and the working air distances or tool insulation between parts and/or workers at different electric potentials. 2018-05-01 · Minimum distance estimation without rank restriction. Assumption PR implies that the matrix Ξ n is reduced rank.

See other definitions of MAD. Other Resources: We have 313 other meanings of MAD in our Acronym Attic. An unqualified person shall maintain a minimum approach distance of 4 feet from all energized equipment for voltages of less than 600 volts, unless accompanied by a qualified person. For voltages above 600 volts, the minimum approach distance for an unqualified person, unless accompanied by a qualified person, shall be those Abstract. Describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV and 800 kV.

You can use this page to calculate minimum approach distances for phase-to-phase system voltages exceeding 72.5 kilovolts in accordance with 29 CFR 1910.269 and 29 CFR Part 1926, Subpart V, as follows: Select the method of measurement (feet or meters); 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 Nominal Voltage in kilovolts (kV) Minimum Clearance phase to phase - Boom Lowered Up to 0.75 kV 4 ft.
