Utilization of the IEEE Color Books in the Design of Data Center Construction (Daleep Mohla)

Overview

Daleep Mohla's article in the Fall 2024 issue of 7x24 Exchange Magazine (p. 21) maps the IEEE Industry Applications Society Color Books onto the planning, design and construction phases of a data center electrical system. The Color Books are now known as the IEEE 3000 I&CPS standards. The article is a navigation guide showing which book to consult for which subject, not a calculation method.

Four books stand out in the design phase. The IEEE Emerald Book covers powering and grounding of sensitive electronic equipment (bonding, grounding electrodes and noise mitigation); the IEEE Brown Book covers power system analysis (load flow, short-circuit and voltage stability studies); the IEEE Buff Book covers protective relaying and coordination schemes for fault detection and isolation; and the IEEE Green Book covers grounding system design, electrode selection and stray current mitigation.

For the planning phase the message is clear: I&CPS standards should be used to set design criteria at the planning stage, not added later. As a limit, the article is a short introductory piece without detailed calculations or numerical criteria. The article is therefore useful for giving scope discussions a common vocabulary.

Key points

1. IEEE Emerald Book covers powering and grounding of sensitive electronic equipment: bonding, grounding electrodes and noise mitigation.
2. IEEE Brown Book covers power system analysis: load flow, short-circuit and voltage stability studies.
3. IEEE Buff Book covers protective relaying and coordination schemes for fault detection and isolation.
4. IEEE Green Book covers grounding system design, electrode selection and stray current mitigation.
5. I&CPS standards should be used to set design criteria at the planning stage, not added later.

Using it in design

• Link each electrical study type in the tool (short circuit, load flow, protection coordination, grounding) to its IEEE reference in tooltips and report headers.
• Add a checklist that design deliverables include these studies before issue for construction.
• Reference the Buff Book for selectivity and protection studies and the Emerald and Green Books for grounding.

Who should read it

Data center electrical designers, commissioning teams and project managers who define the scope of electrical studies.
