Transposition In Transformer Windings

BY M.M.V. RAVINDRA

TRANSFORMER

CORE (CRGO)

WINDINGS (COPPER)

NO LOAD LOSS

I²R + WINDING STARY LOSS

STUCRURAL INSULATION PARTS(MS) (PB & DLW) STRAY LOSS

DILECTRIC LOSS

MAGNETIC FILED WICH COMPLETS ITS PATH WITH WITHOUT COMPLETELY PASSING THROUGHT CORE, PASSES TROUGH AIR(OIL), COPPER, MS etc.

LEAKAGE FILED IN TRANSFORMER

LEAKAGE FILED IN TRANSFORMER

WHEN LEAKEGE FILED CUTS THE STRUCTURAL PARTS ( OF MAGNETIC MATERIALS, Ex.MS) EDDY CURRENTS WILL FLOW THROUGH THEM .WICH CACUSES EXTRA LOSSES CALLED STRUCTURAL OR STARY LOSSES

WHEN LEAKEGE FILED CUTS THE COPPER CONDUCTOR EDDY CURRENTS WILL FLOW THROUGH THEM. WICH CACUSES EXTRA LOSSES CALLED WINDING EDDY LOSSES

Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages.

Say, EA = 11.2 kV EB = 11kV EC = 11.1 kV
