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 ...

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-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

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 ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...
