Infrared technology: How to use thermal imaging to check electrical systems
Every year thousands of electrical workers are injured or killed while at work. Standards such as NFPA 70E aim to keep workers safe through six strategies. With a goal of understanding how to use thermal imaging to check electrical systems, this 20-minute Plant Services Fundamental first reviews facts and figures of electrical safety. It continues with a discussion on the anatomy of an arc flash and the severity of arc flashes. It then identifies how thermography is useful, reviews indirect vs. direct temperature measurements, and the use of thermo imaging to identify electrical faults. Finally EMSDs are reviewed for use in energized electrical equipment.
