To manage the edge data, the utility deployed Fledge, the Linux Foundation’s industrial IoT edge project supported by Dianomic Systems. Fledge is an open, industry-wide solution for monitoring the Internet of Things that collects data from sensors, processes it at the edge, alerts and delivers it to data systems or the cloud. FogLAMP’s Fledge’s open-source architecture provides a rapid, low-cost way to achieve complete visibility into information needed by businesses to operate more reliably and productively.
FogLAMP Fledge collects data from multiple B100s at the substation. It reliably delivers the data to OSIsoft PI for long-term trending, visualization, advanced analytics and event detection
Because of FogLAMP’s Fledge’s open nature, the company was able to deploy it on their existing Cisco 4000 integrated services routers, saving the expense of additional ruggedized hardware.
Lower Costs and Fewer Outages
FogLAMPFledge-based monitoring has enabled the utility to move to a much more proactive maintenance strategy. From OSIsoft PI, they can now detect the warning signs of transformer core, coil and LTC switch failures. Further, PI analytics can calculate cumulative thermal aging of the transformer to forecast life expectancy. Crews can be scheduled to perform maintenance before a failure occurs, resulting in much lower costs and less downtime.
The implementation has proven to be highly cost effective. FogLAMP’s Fledge’s flexibility enabled the company to leverageTcis all its existing edge and back-end systems. Other than sensors, no new hardware was required for the deployment.
The utility plans to leverage FogLAMP’s Fledge’s flexibility to support additional IIoT use cases for field data management, integrating additional sensors and edge-based analytics to identify service requirements. Using Apache Kafka, FogLAMP Fledge will integrate with Oracle ERP to automatically generate maintenance work orders.
