Latest developments in power transformer technology - EE ... transformer is the largest weight and size component in a mobile substation and special designs are necessary to keep the whole structure within the size and weight limits of a standard trailer. Weight is reduced by using higher than normal current density in the coil windings, which reduces the size of the windings and the core.

Electrical Power Transformer: Definition & Types of ...· Power Transformer Definition. A power transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer.Since, there is no rotating or moving part, so a transformer is a static device. Transformer operates on an ac supply.

Transformers | Low/Medium Voltage | ABB & GE are devices used to trade voltage for current in a circuit in electric power applications for uninterrupted operation. Transformers are essential for the transmission, distribution, and utilization of alternating current electric power. GE and ABB have a range of different types of transformers to fit your electric power needs.
