Experimental Assessment of No-Load and Load Losses in Dry- Type and Oil-Filled Transformers

Transformers are essential components in electrical power distribution systems as they enable the effective transfer of electrical energy between different voltage levels. This study conducts a comparative analysis of load and no-load losses in dry-type and oil-filled transformers, essential components in electrical power distribution systems. The transformers are evaluated based on their respective load and no-load loss characteristics to determine the efficiency of the transformers. The results reveal significant differences between the two types: the dry-type transformer exhibits higher load losses and no-load losses compared to the oil-filled transformer, which demonstrates lower load losses and no-load losses. These findings underscore the distinct efficiency attributes of dry-type and oil-filled transformers, with implications for their selection and application in various electrical power distribution scenarios. These experimental findings contribute to a greater understanding of the difference in efficiency between dry-type and oil-filled transformers, aiding in informed decision-making for transformer selection.
