RWE Expands Its Footprint with 450 MW of Battery Energy Storage in Texas

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...

Advancements in Dissolved Gas Analysis: NEI & Gassing Events

One of the most important steps when looking at DGA data is to decide whether the data support the existence of a fault that is actively breaking down the insulation before you try to use a triangle, pentagon, or gas ratio method to identify a fault type. Otherwise, you are diagnosing random...

Hydrogen Monitoring in the Transformer Headspace Compared to Traditional In-Oil Monitoring

By Chris Rutledge, Product Manager, Dynamic Ratings, Inc.

Introduction
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 cost/feature/benefit combinations.

Hydrogen Monitoring
Single or key gas monitoring relies on the use of a sensor for the detection of hydrogen levels either dissolved in the oil or...
