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 ...

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 ...

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

Server and computer system architecture has increased in tandem with power delivery (PD) requirements in recent decades. This complicates regulator design since it necessitates a compromise between ...

While applications for 1-Phase PFC are now familiar and prevalent, the same is not the case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains should be candidates of ...

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 ...

As power density soars, air and single-phase loops hit their limits. A new webinar from Advanced Cooling technologies (ACT) shows how loop thermosyphons and pumped two-phase cooling unlock higher ...

My company is putting together a server room. We've got a massive Eaton/Powerware 9xxx-series UPS for the entire room. It's capable of running higher voltage (looks like 240V instead of 120). What's ...
