METHOD OF ELECTRIC POWER LOSS REDUCTION.

 

FIELD: electrics.

SUBSTANCE: invention concerns electrical equipment. Method is based on current unbalance factor reduction in three-phase feed line and transformer windings. Current leveling in stepdown transformer phases is performed by singlephase load switching from one phase to another in 0.4 kV buses of step-down transformer by switches connecting load to buses and controlled by microcontroller. Load switching is performed on the basis of current unbalance factor minimisation in 0.4 kV buses of step-down transformer.

EFFECT: reduced electrical power loss in stepdown transformer and in three-phase power transmission line feeding step-down
transformation substation. 1 dwg.
