Conference, of which programme you have just opened, is 12th in line of Diagnostics conferences, which became part of our professional life.

Diagnostika `16 2016 Conference on Diagnostics in Electrical Engineering (Diagnostika)

Following the tradition of the previous conferences the main aim of the conference is to interchange the experiences and present the results of the scientific activities of participants. Objective of the conference is to create environment for creating new, and deepen current contacts of the colleagues working in the area of diagnostics of electrical appliances, electrical material science and other field of electrotechnics.

Proceedings contain accepted papers for the conference program. All papers were reviewed by International Technical Program Committee and Reviewing Committee.

The conference is again held in Parkhotel Pilsen, in Pilsen Czech Republic. We believe that once again all of you who have accepted our invitation to attend the conference 2016 Conference on Diagnostics in Electrical Engineering (Diagnostika) DIAGNOSTIKA `16, will find in the program something that interests you, what you will find a new, interesting, helpful and inspiring in your future activities. We expect this year conference as creative and friendly as in the last years.
