In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management. Understanding the trade-offs between Delta and Wye connections enables ...

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, ...

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 ...

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 ...

When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

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 ...

Infrastructure firm Prolec and utility equipment firm Ubicquia have combined efforts to design and market what they call a fully integrated smart transformer. The new transformers deliver real-time ...
