Höfler’s Days, the 12th International Symposium on High-Voltage Technology, will be held on 12 and 13 November  2015 at the Grand Hotel Bernardin in Portorož.

The Symposium will focus on:

We invite experts to participate and share with us their professional experiences by presenting and discussing scientific papers. We invite exhibitors and sponsors to join the symposium and to actively participate and enrich this traditional event.
The following topics represent the core of the symposium:

- Demanding operation of the electric power system accommodating a high share of renewable sources
- Reactive power compensation and measures for maintaining the voltage profile of the HV network
- HVDC electrical power transmission and related special technological features
- Information technologies for the electric power system
- Techniques for reducing the environmental impact of the HV lines and stations
We kindly invite you to dedicate some of your time and join us at the 2015 Portorož Symposium.
