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 ...

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 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 ...

Have you ever wondered why some low-voltage (115-V) power-consuming devices burn out too often? It could be because they are wired to a “high” or “wild” power leg of a voltage supply. These devices ...

Bridgeport Magnetics Group Inc. introduces a new line of dry-type single-phase and three-phase low voltage (600VAC) distribution transformers suitable for industrial, healthcare, commercial buildings, ...

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 ...

Delivering up to 3200 W from a 2U-high package, TDK-Lambda’s TPS300-24 power supply operates from a three-phase delta or wye input ranging from 350 VAC to 528 VAC. The ability to handle high-voltage ...

Joining TDK-Lambda’s TPS power supply series is a 48-V unit that accepts a three-phase Delta or Wye input ranging from 350 VAC to 528 VAC, eliminating the need for step-down transformers and assisting ...
