TUESDAY, 17 OCTOBER 2023
Day 1 – Knowledge Day, Venue: FHNW, Brugg-Windisch, Switzerland
CHALLENGES FOR THE ELECTRICAL GRIDS OF THE FUTURE – SCIENCE, INDUSTRY AND GRID OWNERS PERSPECTIVE
On the first day, mainly customers, representatives/distributors and students from the D-A-CH region are invited to the Day of Knowledge. The program is divided into three sections. First, renowned professors will speak about the challenges for future electrical grids from a scientific perspective. Therein, for example, they will shed light on topics such as extending the service life of primary devices through monitoring or the challenges of operating equipment through DC voltage. In the second section, speakers from grid operators will report on challenges and innovations in the transmission and distribution grids. The third part is the panel discussion with the main topic, “Strengthening the professional environment of electrical grids/high-voltage technology”, with representatives from the industry and the education system. After these substantial contributions, a more relaxed atmosphere shall be created in order to facilitate networking and interpersonal exchange – an aperitif will round off this exiting day. The event will take place at the University of Applied Sciences of Northwestern Switzerland in Brugg-Windisch.
Please note: The presentations will be held in German and simultaneously translated into English and French.

Day 2 – Innovations and Technologies of the PFIFFNER Group, Venue: Kultur & Kongresshaus (KUK) Aarau
INNOVATIONS AND TECHNOLOGIES FOR A SUSTAINABLE ENERGY GRID IN THE FUTURE
The innovative products, systems and services of the PFIFFNER Group are the focus of the second day. These include the new sensor products from HAEFELY, the 420/550 kV bushings from MOSER GLASER, the new DCCT and F-gas-free instrument transformer from PFIFFNER, the new CBDE disconnector generation from ALPHA-ET or system reference projects from PFIFFNER Systems / HAVECO. Experts will provide insight into these new developments and Innovations. The venue for the second day is Aarau. An excursion to a power engineering showcase in the energy canton of Aargau, and a special evening event – “a dinner for all” – will conclude the second day.
Attention: The presentations and guided tours will be held in English. Exception: The presentations in stream 2, from 10.30 – 11.55 a.m., will be in German (CH-relevant projects).
