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 ...

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 ...

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, ...

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 ...

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 ...

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 the “high” or “wild” power leg of a voltage supply. These devices ...

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 ...

Omicron has developed a portable three-phase test system that supports all common electrical tests on power transformers. Weighing just 20kg, Testrano 600 is suitable for routine and diagnostic ...

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 ...
