Electrical distribution asset monitoring: Utility asset management

electrical distribution Landis+Gyr

Power management: Landis+Gyr, a global provider of smart grid solutions, reports that the growth of analytics for monitoring electric distribution assets is transforming utility management strategies. As part of its Advanced Grid Analytics suite, Landis+Gyr’s asset loading solution is being used to identify over and under-loaded equipment, helping utilities prevent equipment failure while optimizing management strategies for critical distribution infrastructure.

“For many utilities, cost-effectively maintaining a reliable grid is a growing challenge, complicated by aging assets and heightened customer expectations,” said Dave Connaker, General Manager of Landis+Gyr’s Analytics Solutions. “Our platform leverages a utility’s existing grid investments in AMI and intelligent devices to provide real-time loading analysis across the distribution grid., Not only does this solution identify asset issues, it also recommends optimized asset management scenarios to proactively prevent outages.”

Operating one of the most reliable electrical systems in the nation, Burbank Water and Power (BWP) turned to grid analytics to meet infrastructure challenges head-on. Implementing a new way to monitor their infrastructure, BWP took action to catch potential outages before they happen by proactively diagnosing distribution transformer issues. As a result, the utility experienced no unplanned outages during a summer heat wave.

“Predictive analytics enables us to deliver services reliably and provides us the opportunity to avoid unnecessary overtime spent on responding to transformer outages,” said Calvin Clark, Electrical Engineering Associate at BWP. “With Landis+Gyr’s analytics asset loading solution, we can now run detailed analysis on transformers, and balance the load when needed to extend the life span of our transformers.”

Landis+Gyr’s asset loading solution enhances utility asset management through:

· Asset Loading Visualization: System operators see a map-based view of asset loading along the feeder from the substation to service transformers.

· Issue Identification: Overloaded assets are identified and prioritized to minimize failure, and improve reliability.

· Business Decision Support: Economic-based assessments for the replacement, proper sizing and location of transformers enable business decisions based on criticality of need.

· Outage Reduction: Reliability metrics and customer satisfaction indexes are improved by better asset management.

To date, utilities have analyzed more than 170,000 miles of distribution lines using Landis+Gyr’s Advanced Grid Analytics power-flow algorithms with data from AMI meters and grid sensors. These capabilities offer a valuable and proven way to leverage smart grid data for planning and improving grid reliability and performance.
