Abstract (en)

An electromagnetic induction apparatus according to this invention is furnished with a short-circuit winding (1c) which is electromagnetically coupled to at least two windings (1a, 1b), thereby to realise a transformer (1A) which effects the shunt reactor function of supplying "leading" reactive power necessary for transmission or distribution lines, without installing a shunt reactor. In another aspect of performance of this invention. an electromagnetic induction apparatus is furnished with a reactor winding (1c) which is electromagnetically coupled to at least two windings (1a, 1b) including a tap winding (1b) and which is inserted between one end of the tap winding and a tap (30), and a tap voltage which is lower than the open-Circuit voltage of the reactor winding (1c) is forcibly applied from the tap (30) to the reactor winding (1c), thereby to generate a desired magnitude of leakage flux (18) between the reactor winding (1c) and the tap winding (1b) and to make the capacity of an equivalent shunt reactor variable.
