How ready is the switchgear industry to abandon SF₆, the ...· However, due to its excellent technical properties, SF 6 has been increasingly used as an insulating and switching medium in HV and MV sectors since the 1950s.One of its main advantages is that it allows for more compact installations, in particular compared to air-insulated switchgear.This is an especially important criterion in urban areas where space is limited.

Calculating Magnetic Flux Density in Transformer/Inductor ...· Note that energy density goes as B^2 / (2*mu), so the energy storage in ferrite is abysmal (almost nil, because mu > 1000 for most), and most filter chokes are wound on gapped, or distributed gap (e.g., powdered iron) materials. An air core choke has the highest energy density, because it won't saturate and because mu = mu_0, as low as it can go.
