JP Morgan Chase & Co – Data Centers


Performed equipment and system surveys, performed electrical studies, generated reports and labels associated with Arc Flash analysis at multiple JPMorgan Chase facilities, including Core Data Centers I and II, at over 1200 pieces of equipment each.

Project Highlights:

Location: Various locations throughout the Banking System
Size: Varied by location

Key Project Elements

Field Surveys
Performed extensive field surveys of existing electrical and mechanical equipment. Recorded equipment ratings, over current protective device ratings and settings, cable information.

Short Circuit Study
Performed data entry and short-circuit calculations for the building power distribution system to determine maximum short-circuit currents which may occur at the electrical equipment during fault conditions. This equipment included substations, switchboards, panel boards, generators, UPS equipment, transformers, enclosed circuit breakers and safety disconnect switches. The voltage ratings ranged from 34.5 kV to low voltage. Studies included determination of worst-case scenario based on up to fourteen (14) switching configurations.

Protective Device Coordination Study
Prepared time-current coordination plots, calculations, and protective device schedules with recommended trip settings for setting in the field by others. The Coordination Study was provided from medium voltage service entrance equipment down to low voltage main breakers in every panel board or largest branch circuit breakers for main lug panels.

Arc Flash Analysis Study
The Arc Flash Analysis was prepared to determine potential exposure to Arc Flash Energy, which is required for the purpose of injury prevention and determination of appropriate levels of PPE. The incident energy and flash protection boundaries will be determined based on the available Standards for Arc Flash analysis (IEEE Standard 1584-2002 and NFPA 70E-2009). Studies included determination of worst-case scenario based on up to fourteen (14) switching configurations.

Arc Flash Labeling
Printed vinyl arc flash warning labels and assisted owner’s facility staff with application. Typical label data included hazard category, required clothing, glove class, approach boundaries, and incident energy.
