2016 Conference on Diagnostics in Electrical Engineering (Diagnostika).
Electrical equipment monitoring and diagnosis are very important for both users and manufacturers. In order to assess equipment conditions, certain periodical tests and measurements must be made and monitoring and diagnosis systems must be installed,
