Abstract

Ovaj rad ističe razlike u dizajnu, procesu izrade i ispitivanja te cijeni energetskog transformatora punjenog alternativnom izolacijskom tekućinom, prirodnim i sintetskim esterom ili biorazgradivim izoparafinskim uljem, u odnosu na snagom i prijenosnim omjerom ekvivalentan transformator punjen konvencionalnim mineralnim uljem. Prednost korištenja alternativnih izolacijskih tekućina u odnosu na konvencionalna mineralna ulja su biorazgradivost i povećana vatrootpornost u slučaju estera, a mane... More povećana cijena i kompleksniji dizajn energetskog transformatora. Less

Abstract (english)

This paper emphasizes differences in the design, the manufacturing process, the testing and the price of alternative insulation liquid, synthetic and natural ester or biodegradable isoparaffinic oil, filled power transformer in comparison to power and voltage ratio equivalent power transformer filled with conventional mineral oil. The advantage of alternative insulation liquids to conventional mineral oils is biodegradability and higher fire resistance in case of esters, while the... More disadvantage is higher price and more complex power transformer design. Less
