The Data Center is mandatory to have a safe power supply, included the stabilizer. The distribution should be design parallel redundant for the normal condition and under power maintenance condition or power interruption.

The best power supply for a data center can be achieved by having more than 1 feeder. For 2 different power feeder have a more complex in the implementation, but it will avoid the single point of failure.

An ideal data center should have a good grounding system. Grounding system is used to provide the same reference for power system. In other hand grounding system also can protect equipment from unexpected spike. Recommended a data center can have a different from building grounding system.
