(NYSE: ESE), today announced it has acquired the assets of Phenix Technologies, the leading manufacturer of high voltage test systems and components. The acquisition positions Doble to build out its high voltage testing and measurement equipment portfolio and further expand into the commercial and industrial sectors. Doble Engineering Company Launches F8000 Power System Simulators June 8, 2021 Configurable next-generation hardware seamlessly blends conventional and digital test performance ESCO Announces Acquisition of Global Utility Supplier May 20, 2021 ESCO Technologies Inc. (NYSE: ESE) today announced that it has entered into an agreement to acquire I.S.A Altanova Group S.R.L. (Altanova), a well-established, leading supplier in the field of advanced condition assessment technologies centered around partial discharge (PD) measurement and analysis, as well as test instruments for electrical apparatus (www.altanova-group.com). Doble Simplifies Insulation System Testing of High Voltage Assets with Spark P3 April 12, 2021 Universal partial discharge and electromagnetic interference analyzer removes the need for expert data interpretation with automatic signal classification, guided measurements and more Doble Brings Condition Monitoring to More Transformers with Calisto H1 April 8, 2021 New hydrogen detector samples transformer oil in real time, equipping utilities with more health information for faster, more confident decisions. Successful application of AI techniques: A hybrid approach November 23, 2020 AI systems provide a lot of promise in the analysis and evaluation of power system data. This article shows some of the benefits of the application of AI, identifying the strengths and weaknesses of the approach, and provides a way forward to apply AI in a meaningful and controlled manner. Oil as a Main Insulation Component in Liquid Filled Power Transformers: Quality and Consistency of Product November 10, 2020 Did you choose the correct oil for your transformer application? This is the one big question I am confronted with after reading through this outstanding article written by the three authors, Lance Lewand, Eileen Finnan, and Melissa Carmine-Zajac. All of them are highly respected in the industry. Interesting to see the long road oil analysis has come and the progress that has been made in the transformer oil industry, to ensure a high-quality product fit for a specific purpose. The criteria are set out to guide us to evaluate the insulating fluid when considering a fit candidate for lifetime optimization and reliability. Think of a number… November 5, 2020 An asset health index (AHI) summarises a lot of disparate data into a single value in order to estimate the condition of the asset, such as a transformer. The big question is: does everyone understand what the AHI really means? Technical information used to derive an AHI is lost. At the same time, looking at the AHI value, the end-user can get a feeling that they know all they need to know, which sometimes can be misleading. Doble Boosts Transformer Testing Productivity, Accuracy and Performance with New M5500 Sweep Frequency Response Analyzer November 2, 2020 Next-generation SFRA instrument dramatically reduces testing time and maintenance costs while ensuring high-quality measurements in the field. Impact of SFRA Setup Issues on Transformer Frequency Response November 1, 2020 Sweep frequency response analysis (SFRA) is a popular test to confirm the mechanical and electrical integrity of a transformer. However, the resulting traces can be difficult for field personnel to interpret due to the visual nature of the data. It is more straightforward to compare numbers against prior data or against a stated limit than to interpret subtle differences in SFRA traces. If setup-related issues are not addressed during the testing process, return trips are often required to take additional shots to represent the transformer more accurately. These trips cost time and resources, so being able to identify a setup problem early can keep extra work to a minimum. A trained eye can focus in on a problem area quickly and identify a test setup issue promptly. Such confidence only comes at the expense of hours spent analyzing data. This article discusses common setup problems and their impacts. An Intelligent System for Condition Assessment of Power Transformers October 23, 2020 Health index (HI) approach has been adopted widely as a tool that assists the asset managers to prioritise their plans and actions. However, the conventional computation of HI, which is based on scoring and ranking, has several drawbacks. In this work, the fuzzy logic approach is utilised to build up an intelligent HI system to assess the condition of power transformers based on oil quality and DGA results. PSDcast – Do Cali Wildfires Emphasize Need for Green Energy? October 19, 2020 The episode covers the importance of upscaling infrastructure and maintenance with the transition of renewables against the background of climate-driven weather events, the expansion of microgrids, and how Doble, specifically can support utilities through the transition. Upskilling Power Engineering Workforce: Evolving Skillsets Bring New Opportunities October 14, 2020 A workforce that understands how the power grid works is foundational to the industry’s success. Managing Bushings: From Statistics to Singularities – Where to Focus? October 6, 2020 Managing bushings presents challenges, but also opportunities. In his byline on Asset Solutions, Tony McGrail teams up with Dr. Ronald Hernandez, taking the concept of singularity and applying it to statistical analysis for bushings data. POWER Insights—Advanced Diagnostics to Monitor and Secure the Grid September 1, 2020 Paul Griffin, vice president for professional services at Doble, recently joined with POWER to talk about his work at Doble and the company’s century-long history of support for power generation, as part of the POWER Insights video series. 1 2 3 … 8 Next MEMBER OF THE PRESS?
