This White Paper describes The Isolated-Parallel (“Iso-Parallel” or “IP”) configuration for rotary diesel UPS systems.

This White Paper explores some of the more common Power Usage Effectiveness (PUE) calculation mistakes and myths while demonstrating their impact on PUE values calculated for a specific data center facility design project.

The use of load banks, portable or permanent, during the commissioning process to simulate encountered electrical loads has many facets.  Loads banks provide electrical loading (kW) as well as mechanical loading (BTU’s).  

Operation and maintenance of power circuit breaker equipment involves exposure to potential hazards associated with high-energy electrical supply systems which are typically encountered within data centers.  Switchboard accessory mechanisms are available to provide safety when interacting with this equipment.  

Electricity unlike anything else is not something that can be seen, like the flow of water. Nor can it be smelt, like the breeze bringing odors. It can however certainly be felt usually with disastrous results.  As humans we rely on the five senses of sight, smell, touch, taste, hearing – electricity in general defies the ability to use most of those senses directly. We can however indirectly observe electricity through the use of meters to determine the presence of it.

This White Paper describes factors to be considered when optimizing an existing data center chilled water plant.

This White Paper describes a new approach to large critical power system configuration, which offers significant advantages over current practice for a broad range of commercial applications.
