ABSTRACT
“KONCAR – Distribution and Special Transformers (D&ST) has been facing increasingly complex challenges and market demands recently, and technical development is a key success requirement that drives us to respond more adequately.
Transformer manufacturing does not belong to major environmental polluters, and therefore, does not pose a great threat to the population and nature. Nevertheless, product lifecycle-based thinking at D&ST is manifested in the reduction of the use of natural resources and emissions into the environment, good procurement practices, and recycling capabilities at the end of the product’s life cycle.
As transformers are key structures in creating electricity grids of various voltage levels, and thus an essential link in the global goals of reducing environmental impacts, we strive together with our end customers and partners to develop and apply new technologies. By continuous reduction of transformer losses, usage of new materials with a reduced impact on the environment, and improvement of the circular flow of raw materials, we are working together to support the energy transition towards a carbon-neutral future.
In this manner, we achieve cleaner products and processes, a competitive market advantage and an improved platform to fulfil the requirements of the volatile business climate.”

MIDEL
- Barry Menzies,
ABSTRACT
Sustainability and Circularity are two critical concepts driving economic, industrial and societal change worldwide, and the electrical infrastructure sector is feeling real pressure to adapt, change and improve. Intensifying urban growth, regulatory changes, effective asset management, the drive for integrating renewable generation and battery storage, bottom line financial pressure, and improving human and environmental conditions, are all factors that influence decisions made by utilities, substation designers and transformer manufacturers. Against this background, there is a growing recognition of the role to be played by ester-based transformer insulating liquids. Synthetic and Natural esters have become an established alternative that enable cost and carbon savings in substation designs due to being less flammable and readily biodegradable, while also delivering operational flexibility and the potential to extend asset life. But there are important distinctions to be made, and questions to be asked, about the ester liquid landscape, not least about what happens at end of life? This presentation will answer such questions and more, while clearly delineating a case for embedding MIDEL ester liquids as a key element in delivering a truly sustainable future for people and the places where they live.

EDF
- Jean Sanchez, Senior transformer engineer
ABSTRACT
Sustainable development has been an increasing concern in all technical fields for quite a while. At EDF, a power generation utility, we are looking more and more into detail at how to handle this issue practically. On the hydroelectric side, we aim to calculate the carbon impact of a whole power plant and then up to the transformer. Furthermore, we are still looking at the best way to correctly convert manufacturing and operation losses impact, and we will show a few examples of how we are looking at it.
On the other hand, we have been moving to monitor an increasing number of devices in our power plant (dams, runners, vibrations, temperatures, generators, etc.) for nearly ten years and have developed accordingly an organization that can handle it correctly on a large scale. We will present our organization at three levels of diagnosis, from the plant to specialized teams. Regarding transformers, we will show how we manage oil-dissolved gas analysis (DGA) and bushing monitoring since last year to prevent major failures in service.
Finally, we will present a few cases of how we utilized the benefits of good teamwork to deal with transformer monitoring systems and let transformers with inner faults in service for a specific period.

Koncar-Electrical Engineering Institute
- Vedran Jerbic, Principal Engineer
ABSTRACT
Transformer insulation is known to deteriorate over time due to a range of stresses including electrical, thermal, mechanical, and environmental factors. Transient overvoltages caused by lightning strikes and switching operations can result in electrical stress, while the presence of partial discharge (PD) activity is a reliable indicator of insulation degradation, particularly when its trend is increasing. Power transformer failures are frequently attributed to bushing failures, which can cause severe damage and even result in fires. To prevent such failures, it is essential to monitor all of these parameters and diagnose problems at an early stage, enabling transformer users to plan maintenance activities promptly.

17:00A visit to Dubrovnik City Walls
CITY WALLS AND FORTRESSES
The city ramparts are considered to be one of the most grandiose fortification monuments in Europe.
The Dubrovnik City Walls are the major attraction for any visitor, being one of the best preserved fortification systems in Europe. The 1940-metre long walls include five fortresses and sixteen towers and bastions. The Walls are open for visitors all year round. There are three entrances to the Walls: one next to St. Luke’s Church in the east (opposite of the Dominican Church), one next to St. Saviour’s Church opposite the Big Onofrio Fountain, and one next to the Maritime Museum at St John’s Fortress. A walk along the Walls shows some of the most impressive construction undertakes.There are five fortresses, of which Minčeta, Bokar and St. John’s make integral parts of the Walls, and the other two – St Lawrence’s in the west and The Revelin in the east, stand separately outside the integrated defence system. Located at the highest point of the City, Fortress Minčeta served to protect Dubrovnik from the north.The Fortress is the symbol of Dubrovnik’s defence, the Croatian flag flies on its top at all times, and in the summer the Libertas flag, the symbol of the Dubrovnik Summer Festival is added. In the southwest, Fortress Bokar, also called Zvjezdan, stands at the corner of the City Walls facing St. Lawrence’s Fortress across the bay. It was constructed in the 16th century to protect the small City harbour, the moat around the Walls, and the Pile Bridge. Today it houses a collection of stone fragments from the Dubrovnik area. Built in 1346, St John’s Fortress is the first quadrangular pier tower for the protection of the City harbour from the southeast. A chain across the entrance to the harbour to prevent any unwanted visitors at night was controlled by a winch from the Fortress. An Aquarium is located in the Fortress’s ground floor, while the first and the second floors house the Maritime Museum.At the foot of St John’s Fortress there is a pier with a beacon – the well-known Porporela, a traditional meeting place for romance, a promenade and a swimming spot popular especially with the residents of the Old City. From Porporela one can see Fortress Revelin standing at the eastern entrance outside the City Walls. The stone and wood drawbridge connects the imposing Fortress with the land, and another stone bridge connects it with the City. Surrounded by a moat on three sides and by the sea on the fourth, the Fortress was a part of the City which was effectively impregnable. Although constructed in an earlier period, The Revelin acquired its present day dimensions and shape in the 16th century. The interior of the Fortress and its terraces serve as concert venues for the Dubrovnik Symphony Orchestra and the Dubrovnik Summer Festival. The Culture Club Revelin is a world wide popular place to spend a night to good club music.nd at the Fortress of St. Luke.Source: https://tzdubrovnik.hr/lang/en/get/gradski_vodic/5297/gradske_zidine.html
