Effect Different Limb of Tranformer Core Assemble on Performance

Abstract

This paper described the pe1fonnance of transfonner affected by different limb assembling. The experiment that used to investigate core is no-load, short circuit and load test to find the core loss, copper loss, flux leakage at comer joint and limb and total hannonic distortion of the flux at flux density range from 0.2 T to 1.6 T, 50 Hz. From the result of this investigation shows the core loss of transfonner assembled with 2 limbs is 18.45% and 32.21 % better than the transfonner assembled with 3 and 5 limbs respectively at a flux density of l .6T, 50 Hz. To increase the numbers of core limb assemble will reduce the efficiency of transformer.
