POLYPHASÉ, ÉE

POLYPHASÉ, ÉE
adj.

T. didactique

Il se dit des Courants alternatifs circulant dans plusieurs circuits distincts, ayant même période et présentant une différence de phase convenable. Avec les courants polyphasés, on crée des champs magnétiques tournants utilisés pour le transport de la force.

L'Academie francaise. 1935.
