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 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 ...

Elsco Transformers reports that choosing the right transformer size involves calculating kVA based on voltage and current for ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

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 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 ...

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 ...

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 ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...
