Defect Identification through Partial Discharge Analysis on HVDC: Partial Discharge Fingerprinting

The electricity grid spanning hundreds of thousands of kms is one of the most complex man-made network built in human history. Today, after a century of growth, progress and innovation, the electricity grid is in the process of undergoing another landmark shift in its operation. The introduction of renewable energy sources, especially, offshore...

Dielectric Strength and Thermal Conductivity of Mineral Oil based Nanofluids

In many applications of high voltage engineering, electrical and thermal stresses increase due to an ongoing decrease of product dimensions. In particular, the electrical industry is interested in applying nanofluids in transformers to be able to decrease transformer size and weight. The requirement for nanofluids is to enhance the electrical...
