COLUMBUS, OH / ACCESSWIRE / January 28, 2015 / Weeks after the recent DC Metro train incident that led to one death and 80 individuals being hospitalized, neither the company nor the National Transportation Safety Board (NTSB) can identify the source of the electrical issue that caused the problem. This underscores a need in the railway industry for early problem identification of electrical problems that cause power outages, subsequent delays, and even safety issues.
A predictive technology company in Columbus, Ohio may be able to shed some light on the problem. "When electrical equipment on railway systems fail and cause an outage, it is the result of a process of gradual degradation that has been occurring over time," states John Lauletta, CEO of Exacter, Inc., a predictive technology company that serves the electric utility industry. "A predictive sign of this degradation is the emission of RF signals caused by arcing, leaking, or tracking of electrical components."
Exacter, Inc., has a proprietary technology that can identify deteriorated electrical equipment conditions on any electric system including railway systems, utility grids, substations, or industrial locations prior to a failure. http://www.exacterinc.com/railway-services.
Exacter's predictive technology is currently used by utilities as an early warning system for identifying degraded conditions on the electrical grid. Exacter-equipped vehicles drive along power lines and pinpoint the location of predictive RF Failure Signatur(TM) emissions. These Failure Signatures are identified, located, mapped and investigated. http://www.exacterinc.com/.
"For railways and mass transit systems, our technology would survey lines as a quality control or problem-identification measure," continued Lauletta. "Our Field Engineers would then go to the locations and identify the degraded component.Continued monitoring would identify opportunities for further investigation, component removal, or maintenance by the railway provider." http://www.exacterinc.com/railway-services.
In the utility industry, an Exacter technology survey uncovers 1 problem every 7 miles of line. "We expect finding problems on railway lines will be a much easier process for us because trains are running the lines daily. Our equipment on the trains could provide continuous monitoring, providing early alerts of potential problems, and create a new quality assurance system for the electrical railway system."
Finding root causes of electrical problems is a major challenge in the utility industry, so it is no surprise that as the NTSB and DC Metro continue to investigate the problem. They still have no answer as to the source of the electrical smoke in the cabins. "Troubleshooting electrical systems is a big part of what we do. In the utility industry, we are engaged to define hard-to-find root causes impacting system reliability," concluded Lauletta. "Deploying Exacter technology on rail systems would enable conditions-based maintenance of the electrical system, and identify opportunities to avoid future outages."
Exacter, Inc. is a provider of predictive maintenance technology and services to the electric utility industry and is also being used for the quality assurance of Smart Grid systems, AMR systems, and applications at industrial plants, railway systems, and other electrical environments.
