Welcome

You are hereby cordially invited to participate in the 26th Nordic Insulation Symposium on Materials, Components and Diagnostics (NORD-IS 19), which will be held in Tampere, Finland on 12. – 14. June, 2019.

Who should attend?

The Symposium provides an opportunity for researchers, PhD students and engineers working at research institutes, academia, power industry and power utilities to meet, exchange ideas, research results and practical experience on insulating materials, components, models and diagnostics plus related topics such as apparatus and measuring techniques.

PhD students and young engineers are particularly encouraged to present their work. The symposium language is English and participants from both within and outside the Nordic countries are warmly welcome.

Scope

The scope of NORD-IS 19 includes, but is not limited to the following areas:

NORD-IS History

Nordic Insulation Symposium has a long history, originating back to 1968 when it was started as a symposium on Partial Discharges (Nord-PD). Since then it has been arranged every two years as Nordic Insulation Symposium with the scope covering not only the insulation systems but also all related fields of High Voltage engineering. Despite the traditional name NORD-IS welcomes researchers, engineers and students from all countries.

Preliminary program

Keynote speaker

Invited lecture will be given by Associate Professor Davide Fabiani from University of Bologna. The topic of his speech is “Nanofibrous piezoelectric structures for composite materials to be used in electrical and electronic components”.

Abstract:

Piezoelectric materials are frequently used for energy harvesting and sensing applications. Among these, polymeric piezoelectrics like, e.g., PVdF-based materials, are often preferable for applications thanks to the possibility of realizing electroactive devices in the shape of thin films. However, these films cannot be installed inside other materials since they could incept delaminations with the host material during mechanical stress cycling. On the contrary, if these polymeric piezo are realized in the form of nanofibrous mat, having porosity of about 70-80%, the host material can penetrate between the fibers creating thus an intimate contact, which avoids delaminations to occur. This paper deals with realization of polymeric piezo nanofibers having different geometries, integration in the polymer matrix and measurements of the electromechanical response of the composite materials thus manufactured. Nanofibrous mats of PVdF-TrFE were manufactured thorough electrospinning technique. Two geometries were realized, single-core fibers and core-shell fibers. The formers are very simple to be created and consist of woven-non-woven mats of piezoelectric fibers with planar geometry. The latters are composed of coaxial fibers with an inner conductive core, a piezoelectric nanometric shell and an outer gold-metallization. In this case, the piezoelectric effect can be exerted between the inner core and the outer metallic electrode. Being the mat composed of hundreds thousands fibers the global piezoelectric effect is expected to be very significant even if the amount of polymer is low. The nanofibrous mats have been then inserted in two matrixes, one made of PDMS and one of epoxy resin and the electromechanical response is measured through impact testing and mechanical vibrations. Results showed that the electric response of the both composite materials realized is very high and comparable to that of commercial films, particularly for PDMS composite, probably due to the good elastic properties of the matrix, which allow the fibers to be effectively mechanically stimulated. It can be concluded that the integration of piezoelectric nanofibers in materials like PDMS and epoxies can allow these latters to show electroactive behavior, thus opening up the feasibility of realizing multifunctional smart materials.

Venue

The symposium will be held at Museum Centre Vapriikki in the city of Tampere located in the southern Finland. Conference hotels are located conveniently in Tampere centrum, within a walking distance from Vapriikki and the many attractions of Tampere city.

Tampere

The Tampere Region is one of Finland's fastest growing centres. Tampere has a population of more than 220,000 while there are close to half a million people in the greater Tampere Region. The population of Finland is a little more than five million.

Tampere was founded by Sweden's young monarch, Gustavus III, in 1779. Tampere has a monumental industrial history: the Finlayson cotton mill was the first large-scale industrial enterprise in Finland and it was in fact in Finlayson's factory hall that the first electric light in the Nordic countries was lit.

Today Tampere can be described as a centre of leading-edge technology, research, education, culture, sports and business. It is Finland's third largest city as well as the largest inland city in the Nordic countries. Tampere is located on an isthmus between lakes Näsijärvi and Pyhäjärvi, in a beautiful ridge scenery. The Tammerkoski rapids are a nationally recognized landscape and in the city centre you can also enjoy the awarded lighting at Keskustori Central Square.
