Abstract: High-Voltage Dielectric Spectroscopy (HVDS) has emerged as a powerful nondestructive diagnostic tool for assessing the insulation material condition in high-voltage power equipment such as power transformers, power cables, and transformer bushings. This technique offers unique advantages in terms of voltage frequency range and sensitivity to insulation material microstructure changes, while also providing rich physical information in capturing insulation aging across multiple dynamic scales. This webinar aims to provide an updated summarization of the latest advancements in HVDS application, including measurement, underlying physical mechanisms, modeling approaches, and field-oriented applications in high-voltage power equipment. Challenges related to practical deployment, such as measurement robustness, physical interpretation, and integration with digital monitoring platforms, will be critically analyzed. Finally, future trends and research directions will be discussed, with emphasis on multi-physics integration, AI-assisted diagnostics.
