After the first Ph.D., as part of the HELB student internship, two students graduated from the Faculty of Electrical Engineering and Computing, University of Zagreb and earned their master’s degree. Their thesis will contribute to HELB's digitization path and transition towards a digital engineering company. Filip Pavlovic and Marko Cmuk conducted basic research in the field of Industrial Internet of Things (IIoT) solutions and Augmented Reality (AR) applications in the energy sector. Upcoming technologies, such as digital substations, will change the way we build power plants and substations in the electrical grid, which is why the thesis topics have become our students research work.

Filip's thesis entitled "Secondary distribution substation monitoring system" represents the basis for future research in the field of advanced monitoring solutions in smart grids. Basic research has been made and further development will continue within the company. Asked about plans after graduation, Filip replies:

“I want to stay at HELB and continue to work on this research and its further development. I find it interesting and very dynamic. The wide range of activities like testing, programming, automation, relay protection, design, are very appealing and I most definitely want to stay a part of HELB's R&D team.''
