Abstract

Transformer Bushings are vital components of HV and EHV Power Transformers to connect the Transformer Winding Leads to the Transmission & Distribution Networks. With the significant growth of Power System, there is an exponential growth in requirement of Transformer Bushings. In addition, some ageing networks require replacement bushings to be readily available. There are various national & international standards followed by various utilities and few utilities have their own specifications. This results in various bushing frameworks/models needed to be available to meet such fast-growing requirements. In this presentation, Various Aspects related to Harmonization of Specifications are explained in details and also suggested is the approach which can be adopted by Utilities, thus facilitating easy and ready availability of Transformer Bushings.

Dr. Hugo Campelo, Senior Technical Advisor at NYNAS AB

Abstract

The sustainability is a level-playing field to achive critical societal goals of decarbonization and the return on sustainabaility is much broader than the traditional return on investment indicators used to take investment decisions.

The need for other indicators is evident. Those shall include not only the purchase price but also all the shadow costs/value associated with each different transformer oil. Over previous works we started naming them as enviromental cost indicators.

In last year TMIN in Madrid we presented and debated multiple cases studies of different transformers where such environmental cost indicators have been calculated for the first time using mainly craddle-to-gate data from the LCAs of different oils plus the associated transformer losses during operation.

This year we commit to keep improving those indicators by including more information from the use-phase and the end-of-life of each transformer oil – such as for example oil lifetime or efficient recyclability.

Paola Pachera - Process Engineering Manager at Essex Italy Srl

Abstract

The Project describes the activity of the development of a new thermosetting epoxy resin. This is characterized by improved curing conditions if compared to standard commercial epoxy resins present on the market today.

The study was carried out in cooperation with the R&D Department from IVA France (belonging to SUPERIOR ESSEX and Sister Company of Essex Italy), a consolidated producer of resins and enamels for electrical applications.

The new resin makes possible the optimization of the CTC columns building process thanks to a faster resin solidification (18 hours vs 48 hours) in combination with a reduced curing temperature (110°C vs 120°C).

Thanks to this outstanding result, it is possible to move another step in the direction of the reduction of the emissions, of the energy saving and to a more sustainable industrial process. Finally, the production capacity of the Power Transformers might increase thanks to the reduced curing time of the epoxy.

The new resin was expressly developed upon the request of one of the biggest European plant for Large Power Transformers, HVDC transformers included.

Danijel Brezak - Research and Development Expert at KONCAR – Instrument Transformers

Abstract

Instrument transformers experience a lot of different dielectric, mechanical and thermal overloads during their lifetime. While many of these stresses are addressed through type and special tests outlined in international standards, evolving customer demands and TSO requirements have necessitated the development of new, specialized test methods. These custom methods, along with updates in standards such as IEC 61869-1:2023, have introduced additional testing requirements and revisions to existing procedures. From the perspective of laboratories performing these tests, there has been a notable increase in technical demands and resource allocation. At KONČAR – Instrument Transformers, we actively adapt to these changes by implementing new non-standardized test methods and staying at the forefront of updates to standardized requirements. We are also actively involved in the work of technical committees for international standardization organizations, ensuring alignment with the latest developments. Our expertise spans advanced test methodologies, including Line Discharge Tests, Ferroresonance Tests on Inductive Voltage Transformers (VTs), Internal Arc Tests, Accuracy Class Tests at high frequencies, and Transmitted Overvoltage Tests. By adhering to these rigorous standards, we ensure that KONČAR’s instrument transformers not only meet but exceed the demands of modern power grids. This positions us as international leaders in the innovation, manufacturing, and testing of instrument transformers.
