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 ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

Follow these basic steps to select the best transformer for each phase of your next project. Suppose you've got the job of designing the power distribution for an entire building. At some point, ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

Power factor (pf) is the ratio between real power (P) flowing to the load, and the apparent power (S) in the circuit: pf = P/S. It is a sinusoidal waveform and therefore expressed as a dimensionless ...

Editor’s note: I am pleased to bring you this excellent tutorial by Steve Subiry, Global Products Manager for Magnetics at Eaton. Enjoy. Magnetics are essential components in power topologies but they ...

All isolated DC-DC power converters include an input filter, output filter, transformer, primary-side switch(s), secondary-side rectification and a controller. The controller can be referenced to ...

Power transformers are one of the most critical and expensive assets in electric transmission and distribution. An in-service transformer failure can have far-reaching consequences: extended outages, ...
