Abstract

This thesis, titled "Comparative Analysis of Conventional and Non-Conventional Current Transformers: Advancements, Applications, and Implications for Modern Power Systems," examines the performance and challenges of conventional and non-conventional current transformers (CTs). Conventional CTs, while reliable in traditional power systems, face issues like core saturation, mechanical stress, and environmental limitations, making them less suited for modern, dynamic systems. Non-conventional CTs, such as optical and Rogowski coil-based transformers, offer higher accuracy and better adaptability, especially in digital applications like smart grids. Through experiments, the study compares the thermal performance, accuracy, and load-handling abilities of both CT types. Results show that while conventional CTs are reliable, they struggle in environments needing precision and flexibility. Non-conventional CTs show promise but have challenges in terms of integration and calibration with existing power systems. The thesis concludes that future research should focus on dynamic impact testing, better calibration methods, and ensuring the durability of non-conventional CTs. These improvements are essential for the future of power systems that require greater accuracy, efficiency, and adaptability.
