A Versatile System for Electrical Treeing Tests under AC and DC Stress Using Wire Electrodes
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2011

An alternative method to evaluate electrical treeing in solid dielectric materials is presented. Here the test sample utilises a wire electrode for creating the necessary high divergent electric field. This introduces a different preparation method and several of the disadvantages with the traditional needle sample can be avoided. Together with the test object a versatile test setup for both AC and DC measurements is illustrated. This alternative method has proven successful and an evaluation thereof as well as a comparative study between the two electrode systems is included.
