Transformers and switchboards

The input power for the Critical IT Loads requires a source of 380-415V, 3phase Wye power. This may require custom transformer(s) be provided to derive this power if it does not already exist at the source. In addition to the overall loading and KVA size, considerations should be given to the Harmonic Content of the installation when specifying the K-Factor of the transformer(s). Alternatively, Harmonic Mitigating Transformers might be used to passively cancel the harmonics generated by the IT Equipment.

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

On-site connections may include:

Main facility power to the primary side of the transformer

Transformer to the switchboard

Switchboard assembly to the HP POD 240a

For connection information, see the HP Site Preparation Drawing Package (on page 6).

Preparing the site for power

The customer must provide and submit the following fully coordinated drawings showing the exact routing, plan view, sections, and elevations, for approval before beginning site preparation:

o Coordinated underground conduit routing drawings o Site pad drawings

The HP POD 240a requires an external transformer and switchboard. If the customer provides their own transformer and switchboard, they must also provide HP with the engineering drawings.

IMPORTANT: To provide power to the HP POD 240a, external transformers and switchboards may be required. This equipment must be designed and installed to adhere with local, state, and national codes, and installed by contractors with licensing required by the local jurisdiction; city, township, and state.
