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 ...

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 ...

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 ...

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 ...

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, ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

In the quest for more power efficient data centers, is there any trend in the US to move to 240V/415V three phase power distribution in the data center racks? (or 230V/400V) I would not expect the ...
