Big data analysis for power and utilities boosts transformer performance

August 29, 2018 // By Nick Flaherty
Two US companies have teamed up to develop a range of modular cloud-based digital asset management and monitoring tools for the power and utility industries.

Doble Engineering is working with transformer supplier Efacec on the system to help power and utility organizations montior systems and manage risk more effectively. The two companies have created a range of online condition monitoring and diagnostic packages for transmission, distribution, renewables, industrial and power generation. 

"In the world of big data, the real value comes not just from capturing the critical insights, but from making the data actionable. That's what drives high performance and protects against risk," said Bryan Sayler, president of Doble Engineering. "Together with Efacec, we are bringing reality into asset health management by providing meaningful transformer data in a timely manner that equips teams to make sound, data-based decisions around asset health."

The flexible and scalable joint offering includes monitors for dissolved gas analysis, such as Morgan Schaffer's range of Calisto analyzers, direct hot spot measurement by embedded fibre-optic sensors, partial discharge and Doble's bushing monitor. Other analogue and digital contextual data can be integrated through an aggregator such as the Efacec Smart Aggregator and doblePRIME iO. Doble Engineering and Efacec can also provide a centralized data management solution that gives a comprehensive view of the entire asset fleet via Efacec System Point and dobleARMS.

The combination boosts asset management of power transformers by combining relevant, synchronized asset health data with expert critique and high-quality condition-based field services. The entire system is designed to fit with existing or new power transformers and will help teams better understand the real condition of transformers while enabling optimized performance management.  

"Doble Engineering and Efacec both have long histories of delivering intelligent, reliable solutions for the power industry and we are very excited to be working with the Doble team in addressing the data and asset health challenges faced by global utilities," said Ricardo Ribeiro, manager of asset management and digital transformation at Efacec. "By getting valuable and scalable data insights at every stage of the transformer lifecycle, teams will be much better equipped to protect
