Voltage conversion
A transformer transfers alternating-current power through electromagnetic induction, changing voltage without changing the supply frequency. Step-up and step-down duties connect generation, transmission, distribution and utilization.
Configuration choices
Common distinctions include single- or three-phase construction, oil-immersed or dry-type insulation systems, and two-winding, three-winding or autotransformer arrangements. These configurations are selected for different network and installation requirements.
Development priorities
Lower losses, suitable environmental performance, compact layouts and condition monitoring remain important development directions. Temperature and partial-discharge information can contribute to an equipment condition assessment.
