Overview

My PhD research has expanded my capabilities in high-voltage diagnostics. I developed innovative, time-resolved techniques that combine traditional partial discharge measurement with multi-sensor approaches, including ultra-high frequency sensors, optical detection, and electrical measurements, to accurately capture the magnitude and timing of electrical discharges. My work explores how various voltage conditions, polarity reversals, and electric field fluctuations affect corona and surface discharges, while assessing the performance of environmentally friendly SF₆ alternative gases. This integrated research not only refines diagnostic methodologies but also provides critical insights for designing safer, more resilient, and sustainable high-voltage systems.

Gained from my previous Master’s studies at Cardiff University, I received a rigorous foundation in high-voltage engineering by teaching me how to design and analyse modern power systems. I learned to understand the evolution of electrical networks into smart, active grids; to implement advanced network management and demand-side strategies; and to design robust protection schemes for both transmission and distribution networks. My projects also instilled critical skills in modelling distributed generation impacts, performing comprehensive risk assessments, and utilising condition monitoring and forecasting techniques to predict equipment degradation. Simultaneously, my hands-on training in power electronics, magnetic sensor design, renewable energy integration, and power flow analysis empowered me to address real-world challenges—such as optimising energy demand for net-zero targets and planning future energy supply mixes.
