METHOD OF TRANSFORMER CONNECTION Russian patent published in 2013 - IPC H02P9/00 H02P1/00 

FIELD: electricity.

SUBSTANCE: method of transformer connection consists in using a low-capacity transformer, the primary winding of which is connected with a source of power, and the secondary winding via an RL-circuit is connected with the secondary winding of the power transformer, a synchronisation device, performs synchronisation at the side of the primary winding of the power transformer and the power source. On the primary winding of the power transformer three-phase voltage is generated, which is equal in frequency and is close in amplitude to voltage generated on the power source.

EFFECT: reduced value of a start-up current of a power transformer, improved quality of power in a grid.
