Abstract

PURPOSE:To avoid over concentration of electric field on a current conductor drawn out of the lead out part of a stationary induction apparatus even if the sectional area of the current conductor is large enough only to bear the load current by winding shielded wire around the conductor. CONSTITUTION:Lead out part 14 of the end of a high voltage coil 2 is composed of a conductor 16 with insulation covering 15 and a shielded wire 17 wound around the conductor 16 using the conductor 16 as an axis. The potential of the shielded wire 17 is determined by connecting at least one end of the shielded wire 17 to the high voltage part or by the composition by which the specific voltage is controlled by capacitor potential dividing. As a result, as the conductor 16 of the lead out part 14 is surrounded by the shielded wire 17, the over concentration of electric field on the conductor is avoided, so that the sectional area of the conductor 16 can be just large enough to bear the load current.
