How Do Power Transformers Work?
Power transformers transfer electrical energy through a changing magnetic field. An alternating voltage applied to one winding establishes alternating magnetic flux, which induces voltage in another winding linked by that flux. When a load is connected, current flows in the output circuit and the transformer draws the corresponding input power, together with its losses. The […]

Compact Substation Type Tests: What IEC 62271-202 Reports Should Show
A compact substation type test is evidence that a defined prefabricated substation design was evaluated against specified requirements. Under IEC 62271-202:2022, the central purchasing question is not whether a supplier can show a document bearing the standard number. It is whether the tested assembly, ratings, enclosure, equipment arrangement and test conditions are relevant to the […]
