Arc Flash & Coordination Studies
One similarity across most Healthcare facilities is that their electrical systems are both complex and highly critical to the lives and safety of patients and workers. An arc flash and coordination study will ensure that you know your facility is safe.
Per NFPA 99, all Type I occupancy facilities are required to have an arc flash and coordination study completed and implemented on their electrical systems. With 10 degreed electrical engineers on staff, Tanner Engineering performs these studies in house, providing a hands-on approach to these critical tasks.
We verify every piece of equipment in the electrical system in the field and bring that information back to the office to perform the studies. We then provide the facility with the resulting reports and install the required labeling. No third parties involved.
Arc Flash and Coordination Study
Sharp Grossmont Hospital – La Mesa, CA
The first portion of Sharp Grossmont Hospital was completed in 1955. Since then, there have been more than 10 major additions to the facility, and for more than 30 years, there has been at least 1 construction project in progress at all times.
The electrical system has undergone expansion and change in order to keep up with the ever-changing facility. Some of that expansion has included new electrical distribution from 12 kV switches, to transformers, transfer switches, switchboards, and panel boards. While other modifications to the electrical system have resulted in adding panels in areas that had no capacity for a new construction project. The resulting electrical system is comprised of more than 1,000 pieces of equipment.
In order to ensure the full coordination of the system and provide arc flash labeling on each piece of equipment, Tanner Engineering was engaged to perform an Arc Flash and Coordination Study of the entire electrical system on campus.
Tanner located and documented each piece of equipment and each feeder and then modeled this extensive system within SKM. We then revisited the site and installed arc flash labels on each piece of gear. Tanner Engineering performed each step of the process without engaging any third parties, thereby providing the facility with a level of accountability second to none.
