Dissolved gas analysis: addressing the challenges of collecting samples
BY DONAL SKELLY, GE’s Digital Energy business
Dissolved gas analysis (DGA) is a technique for identifying and quantifying the gas formed in oil-filled electrical equipment because of either the natural aging of oil and paper or accelerated aging due to a fault. The quantity and constituents of the gas generated by aging or a fault differ dramatically, but both are important to utility managers who want...
This summer, Aevitas Inc. announced a partnership with Calumet Specialty Products Partners, L.P. to bring improved access to premier transformer oil products across Canada. Aevitas will exclusively distribute Calumet’s new line of Caltran™ insulating oil — Caltran C50 — in...
Turning electrical assets into green machines BY RONNY FRITSCHE & GEORG PUKEL, Siemens AG Transformers are one of the most important components of energy grid systems. They enable the efficient transport of electric energy from the location where the energy is generated to the location where...
IntroductionThere is more to DGA interpretation than comparing the latest gas concentrations to limits in a table or plotting them in a triangle or pentagon to identify the apparent fault type. We have found that the whole DGA history of a transformer must be considered when interpreting its most...
As a philosophy and English major who has spent the last 20+ years working in the utility industry,I often come across topics that challenge me because I don’t have a science or engineering background. This article is an exploration of the basics around online DGA monitors, to better...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
In a significant move for the renewable energy landscape, RWE, a leading global energy company, has announced the addition of 450 megawatts (MW) of battery energy storage capacity in Texas. This expansion underscores the growing importance of energy storage solutions in enhancing grid reliability...
In the rapidly evolving landscape of power grid management, digital twin technology is emerging as a game-changer for substations. By creating virtual replicas of physical assets, digital twins bridge the gap between the physical and digital worlds, enabling enhanced operational efficiency and...
In a significant shift, the Federal Energy Regulatory Commission (FERC) has decided to abandon its transmission incentives policy, particularly the construction work in progress (CWIP) incentives. This decision marks a pivotal change in how transmission projects are financed and regulated,...
The utilization of online dissolved gas analysis monitoring has proven to be one of the most effective predictors of overall transformer health and condition. A wide range of monitoring systems are available, offering multiple costs, features, and benefit combinations. Hydrogen MonitoringSingle or...
There are two standard methods from ASTM International: D877, Standard Test Method for Dielectric Breakdown Voltage of Insulating Liquids Using Disk Electrodes, and D1816, Standard Test Method for Dielectric Breakdown Voltage of Insulating Oils of Petroleum Origin Using VDE Electrodes. VDE stands...
