The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role ...

Magnetic components, particularly transformers operating at high frequencies and voltages, are intrinsically influenced by parasitic capacitance. This unintended capacitance between conductive ...

All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

The application of electromagnetics has been in practice for more than a century: In 1831, English chemist and physicist Michael Faraday invented the transformer, although he called it an induction ...

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...
