Three Phase Power Transformers have been designed as three-phase electricity is used so often for power distribution systems. Amar Transformers Pvt. Ltd. Manufactures Three Phase Power Transformers. Amar Transformers Pvt. Ltd. Is an ISO 9001-2000 awarded company that manufactures wide range of transformers. Three Phase Power Transformers are available in two types, regular and special. Regular single-phase transformers can be ganged together to transform power between two three-phase systems in a variety of configurations, eliminating the requirement for a special three-phase transformer. However, special three-phase transformers are built for those tasks, and are able to perform with less material requirement, less size, and less weight than their modular counterparts.
