ANSI IEEE standards for power quality grounding state: IEEE 142-5.1 The grounding of sensitive electronic equipment, such as computers…. and similar electronic equipment, has been found to be one of the important items in achieving useful operation from these systems.   ANSI IEEE also states: IEEE 142 (4.1.2) The ground resistance of the ground electrode

The Enseva facility in Hiawatha has a state of the art deep earth grounding system. This deep earth ground meets the IEEE 142 standard of less than 5 ohms to earth. This deep earth ground performs the following: Limits voltage in a electrical distribution system to definite fixed values Limits voltage to within insulation ratings

Enseva Hiawatha continues to implement radically different state-of-the-art equipment.  These green transformers are responsible for taking higher voltage power from redundant utilities or generators and lowering them to more appropriate ranges that IT equipment can handle.  These green transformers are currently the worlds most efficient units operating at an impressive 99.1% efficiency!

The custom developed chiller system used to maintain temperature in the high density Hiawatha datacenter arrived today. The high wind perimeter wall will be added at a later date.

The ceiling has been painted and today the electricians start to install the Enseva proprietary suspension system that will be used to hold all electrical, cooling and data infrastructure throughout the facility.

Enseva Hiawatha received two of the twelve 1.5MW generators
