Abstract :
The most commonly used types of uniform-field electrodes for dielectric strength tests in dielectric liquids are briefly recalled and analyzed, and the most significant criteria for the design of electrodes for the above purpose are reviewed and discussed. A new kind of uniform field electrodes which seems to be more suitable than the usual ones in regards the above criteria, is then presented and the procedure for the design of electrodes of given gap and uniform field area is fully described. Finally, the results obtained in extensive series of tests performed with three sets of electrodes of different uniform field area are briefly reported and discussed.
