iFortress White Paper: Improved Data Center Cooling Efficiency within a Sealed Enlcosure
In addition to the note efficiencies in the white paper below that are gained by a sealed iFortress enclosure, there is virtually 100% efficiency gained on the energy that is consumed to maintain a positive level of pressure within a conventionally built facility. This expense, along with the installation of vapor barriers within conventional walls, is a common practice used to maintain as “humidity free” an environment as possible for data centers, as well as reduce the infiltration of dirt and dust from adjacent spaces. Because the panels are engineered to withstand elements such as humidity and the assemblies are sealed, the pressure established within the assemblies is constant, and therefore, there is no need for these pressurization efforts. As such, this consumption of energy, used as a form of standard operating procedure in data centers, is eliminated in its entirety, thereby netting a 100% efficiency gain.

Thomas & Betts Field Trial White Paper:
Current Technology Surge Protection System for Lighting Protection
Many companies have made the transition to energy efficient lighting and are benefitting from lower electric bills. However, many of these same companies have seen an increase in their lighting maintenance costs. Thomas & Betts contacted one of these companies to see if we could help determine a root cause for the increased lighting maintenance costs and to investigate potential solutions. The company agreed to let us assistant them and provided ten stores for the evaluation. Several of the stores selected were stores that had seen the most increase in lighting maintenance budgets since switching to energy efficient lighting ballasts.

Powersmiths White Paper: K-Factor Can be a Misleading Power Quality Indicator
This paper looks at the evolution and measure of success of different harmonic treatments applied in commercial buildings. Typical levels of voltage distortion are described in light of extensive harmonic data collection at North American sites over several years at hundreds of electrical panels and transformers. The field data shows that contrary to the popular belief, doubling the neutral and derating or k-rating the transformer does not properly address the harmonic issues facing today’s buildings.

Powersmiths White Paper: Life Expectancy of Powersmiths Transformers
The operational life of a Transformer is primarily determined by the life of its insulation system (materials used to insulate the conductors in the coils and the coils from the core) with abnormal conditions such as sustained short circuits, corona discharge from fast transients (e.g. lightning)* and mechanical damage excepted; Copper, Aluminum and Steel are stable at well beyond the normal operating temperatures of the Transformer. It follows therefore that for longest life a superior insulation system must be employed.

Powersmiths White Paper: System-wide Harmonic Correction
A hybrid solution consisting of a parallelconnected electronic filter at the point of service
and locally applied phase-shifting distribution transformers delivers a cost effective and
complete system-wide harmonic correction solution. This approach takes advantage of
transformer configurations placed close to the loads to cancel commonly found characteristic harmonic currents by creating quasi higher pulse systems and then uses a small electronic filter to address the residual harmonic currents inherent to multi-pulse systems.

Powersmiths White Paper: Transformers and Associated Losses - The Opportunity for Savings
Low voltage distribution transformers have historically been considered as one of the more
efficient parts of the electrical infrastructure. However, published data shows that real world
transformer losses are much higher than published manufacturers’ data suggests. This paper tracks the origin of the higher losses to the increasingly electronic nature of connected equipment, and looks at the impact on different transformer types including low temperature rise, Energy Star and K-rated. This paper explains the different approaches and compares them to Powersmiths transformers, which have been 3rd party validated at Oak Ridge National Lab, a US DOE test facility, to hold 98% efficiency under electronic equipment load profile and dramatically reduce unwanted system voltage distortion.

Powersmiths White Paper: Improved Data Center Efficiency within a Sealed Enclosure
Today’s modern data centers are large energy consumers, particularly with the movement toward higher density servers. As a result of the large energy consumption and the increased awareness of energy savings initiatives not only from the pure economic sense, but from the sustainable design perspective through the U. S. Green Building Council LEED programs and the joint U.S. Environmental Protection Agency/U.S. Department of Energy, Energy Star program, concern of improving data center cooling efficiency is rapidly increasing.

Server Technology White Paper: JITC Tested Cabinet Power Distribution Units for DOD Information Technology and National Security System Applications
The Joint Interoperability Test Command (JITC) is an independent evaluator of information systems deployed within the Department of Defense (DOD) and is one of the responsible organizations that conducts Information Assurance (IA) and Interoperability (IOP) testing of network devices that will be connected to the Global Information Grid (GIG).The products tested feature intelligent IP addressable power distribution, remote management for rebooting connected devices, input current monitoring, environmental monitoring for temperature and humidity, and serial port console access. This testing was conducted to verify Server Technologies security protocols and viability to operate on government computing and networking environments such as the GIG. As well as having these products incorporated into the DOD network environment and/or future DOD acquisition programs by meeting the standards of DOD Directives 8500.1 and 8500.2.

Tier Ratings
Tier Ratings White Paper: Tier Classifications Define Site Infrastructure Performance
Widely accepted within the uninterruptible industry, The Uptime Institute's Tier Performance Standards are an objective basis for comparing the capabilities of a particular design topology against others or to compare groups of sites. This paper defines a four Tier system providing discussion and illustrations of each classification.
