The conference ICDL 2014 is a sequel in the series of conferences intended to provide a forum for professionals, engineers and researchers dealing with liquid dielectrics to present and share their research results, obtained knowledge and experience and in this way to spread progressive ideas. Traditionally this conference attracts in first place all those who are deeply involved in study of behaviour of known materials, developing and introducing of new materials as well as implementing of dielectric liquids in high voltage equipment and devices in general. A steadily increasing interest in the research of environmental impact of dielectric liquids was noticed in some outstanding papers presented to the participants of last conferences. A keynote lecture entitled Liquids in High Voltage Equipment, homage to Hans Tropper, will be given from Professor Ernst Gockenbach. Corrosive sulphur as a still more difficult and worrying problem in power transformers will be presented and discussed in a special lecture given during the conference by convenor of the CIGRé WG A2.40. The Conference will provide an opportunity for the participants to make new acquaintances and strengthen friendship.
