Abstract

Transformers efficiency is crucial in the overall efficiency of an industrial system. Today's transformers core is commonly made from gain-oriented silicon steel. Silicon core has significant loss which is constant and continuous loss for the generation and distribution companies. New core material, amorphous core, arises in the market today. However, none in the Philippines had enough research and prototypes for the performance of amorphous core to be mass produced in Philippine market. FEDCOR, the number one distributor of transformer of Manila Electric Company (MERALCO),conducted research and built prototypes for 25kVA and 50 kVA transformers using silicon and amorphous core. The cores were designed in such the transformer ratings and other components were almost alike. No-load test on the secondary side of the prototypes were done initially and after the transformers were fully tanked. Results showed that amorphous has reduced transformer core loss with respect to that of silicon. Efficiency was also improved since there was huge difference on the no-load loss of two transformer types As for the cost, it was calculated that amorphous core transformer had higher first cost but has lower expenses of losses in its operating years. It is concluded that amorphous core is a good alternative for silicon. Also, greater benefits of conversion of Philippines to amorphous will be realized upon considering the results of the study.
