Globe Life Field is a state-of-the-art ballpark stadium that will replace the existing Globe Life Park across the street. The ballpark is 1.7 million square feet, has an attendance capacity of 40,000, and a total construction cost of $1.1B. RWB Consulting Engineers provided a number of services on this exciting project for the DFW Metro area.
RWB provided electrical short circuit coordination and an arc flash study on the project. The short circuit study models the current that flows in the power system under abnormal conditions. The model will determine the prospective fault currents in the electrical power system. The accuracy of these results is essential because they are used to specify electrical device withstand and interrupting ratings.
The protective device coordination study has two purposes. First, to ensure that the protective devices open or “trip” in a timely manner to minimize damage to system components. The other goal is to allow protective devices to open in a specific order so that a facility sees a minimal interruption of electrical service under a fault condition.
The arc flash hazard analysis was performed to estimate: (1) arc flash boundary distance, (2) arc flash incident energy at typical working distances, and (3) the required level of Personal Protective Equipment (PPE) at each equipment in the distribution low voltage systems.
