Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...

This whitepaper compares single phase and three phase circuits from the component count, stress level and complexity standpoints. The document shows that on most cases, single phase circuits are the ...

Asma Aziz is a member of the Institute of Electrical and Electronics Engineers. If you’re building, renovating or planning to install a solar battery, your builder or installer might ask whether ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

In this paper, the authors develop a program for the design of transformer using Matlab. The proposed methodology has many advantages for transformer manufacturers, since they can save design ...

There are many reasons why one would want to measure voltage and current in a project, some applications requiring one to measure mains and even three-phase voltage to analyze the characteristics of a ...

The major drawbacks of conventional diode or thyristor rectifiers are overcome by active power factor correction; this further provides additional benefits. Operating principles and features of single ...

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 ...

The article in the March 3 issue of The News dealt with the secondary windings of a Delta service transformer with one winding center-tapped to the ground. The article stated that the power-leg or ...

Linemen from North Carolina municipals practice three-phase transformer banking using the new Load-Trainer II Transformer Simulators. When apprentice linemen step out into the line trade, utilities ...
