Spocitat sa da, len realizacia je horsia...
vinut 100-ky zavitov drotu s prierezom vodica npr.185 mm^2 nie je celkom 
zabava, cele 3x ( 3 fazy, pripadne aj pre nulak)...
Ak to nie je len indukcnost, ale najjednoduhsi LC ( gama, Pi, alebo T 
clanok, ... ) tak aj baterie kondenzatorov
so zatazou na prislusne prudy.
Realizovatelne to samozrejme je, ale ako som pisal pred tym, tak nikde 
sme to nepouzili, kedze cena nebola "stravitelna"
