LiveWire Innovation is a technology company that enables system operators and equipment manufacturers to ‘see’ into their electrical infrastructure and systems while in use. The ability to monitor live systems without interrupting operations enables the detection and location of hazardous and noteworthy electrical faults, such as open and short circuits and hard to find intermittent events, like arc faults. Since LiveWire’s products can work on energized systems, they also hold the potential to characterize normal modes of operation to then look for changes that represent possible failure points.
LiveWire’s patented Spread Spectrum Time Domain Reflectometry or “SSTDR” is a unique technology that uses very low amplitude signals, pseudorandom codes and innovative correlation techniques to look for impendence changes in energized cables at distances of up to 4 miles and with fault location accuracy of 98%, which can mean within feet or even inches of detected events.
Interest in SSTDR started with the aeronautics and rail industries, but has spread to a much wider set of markets given the growing need to monitor live systems for safety, security, reliability and the collection of data. The operational benefits of continuous monitoring with precise fault location includes increased revenue through less downtime, enhanced safety for employees and customers, reduced maintenance costs and theft prevention. For many customers, the ability to characterize their systems’ base line performance and monitor for changes holds significant potential.
