ABB DISTRIBUTION TRANSFORMER UNIT AND GRID LOSSES

With their widespread application and continuously energized state, distribution transformer losses make up a considerable fraction of the total losses incurred in distribution systems. Even a minor increase in transformer efficiency would lead to significant energy savings. Two types of transformer losses are commonly evaluated for loss reduction: core or no-load losses and coil or load losses. Transformer no-load losses can be reduced by using superior grade magnetic core steel materials or optimizing their geometries. However this may increase load losses and vice-versa. Transformer loss reduction is therefore an optimization process involving physical, technological, and economical factors tempered by life-cycle performance analysis. ABB transformer designs make evaluations for maximizing efficiency, taking into account initial cost of the transformer as well as life cycle costs including losses.including losses.

ABB – THE LARGEST SINGLE MANUFACTURER OF DISTRIBUTION TRANSFORMERS

ABB transformers are providing faultless service for over five decades across the world and offer solutions for every need including urban, industrial and rural applications.

In 23 facilities spread across the world, ABB manufactures oil type distribution transformers for indoor and outdoor applications, dry type for reliability and efficiency under critical conditions and transformers for special applications such as for variable speed drives, pad mounted and Booster Transformers
