HP Performance Optimized Data Center (POD) 40c manual Transformers and switchboards

A 1N electrical configuration can be achieved by providing all required electrical feeders from a common power source and from common switchboards, and transformers.

A 2N electrical configuration can be achieved by feeding parallel power paths from independent power sources, switchboards, and transformers.

IMPORTANT: The required neutral must be provided as part of the 800 A 415VAC Y direct connection to the HP POD 40c G2.

IMPORTANT: All 3-Phase Wye feeders for the HP POD 40c G2 require that the neutrals and the equipment grounding conductors remain isolated. Bonding of the two conductors is allowed at the power source only.

Transformers and switchboards

The input power for the critical IT loads requires a source of 380-415V, 3-Phase Wye power. To achieve this input power, a custom transformer might be required if it does not already exist at the source. In addition to the overall loading and KVA size, you must consider the Harmonic Content of the installation when specifying the K-Factor of the transformer. Alternatively, you can use Harmonic Mitigating Transformers to passively cancel the harmonics generated by the IT Equipment.

HP offers several power solutions that include automatic transfer switching, UPS backup, transformers and output distribution switchboards to supply your power needs.

On-site connections might include:

•Main facility power to the primary side of the transformer

•Transformer to the switchboard
