Research & Whitepapers
This Insight Article discusses the best practices for electrical load bank planning during commissioning testing.
This Insight Article presents methods for remote operation of switchboard circuit breakers for arc-flash hazard avoidance.
Principal and Director of Mechanical Engineering, Sam Sheehan, PE discusses containment strategies for co-location data centers. Containment in a purpose-built data center, where an owner can maintain some level of control over IT cabinet configurations, is generally fairly straight forward. However, implementing containment in a co-location data center environment brings with it a unique set of challenges.
Placement of metering devices inclusive of current and potential transformers, relays, protective devices etc. is of paramount importance as it can accurately inform the observer of what is taking place.
As system efficiency and ultra-low Power Utilization Effectiveness (PUE) numbers assume a higher profile, particularly in new purpose-built data centers, the PUE of legacy data centers can sometimes be dismissed or overlooked. But even among data centers a decade old or more, substantial improvements in operating efficiency can be made, often with little or no new equipment.
This Insight Article describes why identifying and correcting abnormal vibrations from newly installed equipment is critical to any project, particularly those projects whose infrastructure equipment serve to support a critical business mission.
Special Considerations When Analyzing Arc Flash Hazard In Systems With Rotary Uninterruptible Power Supply Modules
Rotary Uninterruptible Power Supply (RUPS) modules are technologically complex. This White Paper describes how calculating arc flash hazard on systems containing this equipment requires special attention to the RUPS controls. Otherwise, the arc flash calculations could result in erroneously high values.
Michael Mosman, PE, Vice President and Chief Technical Officer of CCG Facilities Integration Incorporated presents innovative ideas and observations on Medium Voltage Electrical Systems for Data Centers.
This Executive Brief provides some history behind the new ASHRAE 90.1 requirement for waterside economizers in data centers. It also outlines the impact of this requirement on the design, cost, and operation of large data centers.
Isolated-Parallel Redundancy: A New and Better Approach to Large Critical Power Systems Configuration
This Executive Brief describes a new approach to large critical power system configuration, which offers significant advantages over current practice for a broad range of commercial applications.
