Arc Flash at Turkey Point (2017)

The Florida Power & Light Company’s Turkey Point Nuclear Generating Station about 20 miles south of Miami encountered a high energy arc flash (HEAF) in Cubicle 3AA06 of safety-related Bus 3A that ignited a fire and caused an explosion.

Installing a fire retardant wrap around electrical cables inside Switchgear Room 3A at the Turkey Point nuclear plant in Florida inadvertently triggered an explosion and fire. This fault led to an electrical bus failure and a reactor trip.

The electrical fault, which caused an arc flash or small explosion, also damaged a nearby fire door, which may have left other safety systems vulnerable had there been a fire. A plant worker who was in the room was injured and was treated at a local hospital.

What should be done to avoid such incidents in the future:

To ensure safety of your employees and electrical infrastructure it is advised to get the following tests done:

Further, getting an Electrical Safety Audit (ESA) will help customers assist their assets more effectively, with fewer failures and outages, increased safety, and lower expenses.

Introduction Relays are protective elements that help control faults in a power system. Proper relay coordination helps isolate the fault sections from healthier sections in a power system. Being a fundamental part of ensuring reliability and operational continuity, the strategic configuration of protective relays is imperative in the design of a power system. One way […]

Introduction In electric hazards, arc flashes are among the most dreadful threats. Despite their criticality, many myths surround arc flashes. Although IEEE and NFPA continuously strive to enhance awareness, five to ten arc flashes happen in the USA daily. We, at Carelabs understand the importance of maintaining a healthy electrical infrastructure. To help companies […]
