Application of T&D Circuit Segmentation for Improved Resilience—A Texas Case Study
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.ABSTRACT Several lessons were learned from the post‐analysis of 2021 Winter Storm Uri's devastating impact on Texas's electricity grids. Among the lessons was the need for greater granularity and flexibility in how Texas electricity utilities shed load during emergencies, as directed by the local Independent System Operator (ISO), while protecting ...

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Abstract Microstructure homogeneity and grain size reduction are needed to ensure the current uniformity and reliability required in metal oxide varistors for DC circuit breakers. Cold sintering (CS)–a low‐temperature digestive liquid and high‐pressure densification process–has previously shown reduced grain growth, but it is not clear how the lower ...
