ABSTRACT:
The invention relates to a condenser type barrier for field control in transformer bushings and their connection to the conductor of a transformer winding for transformers used in HVDC converter plants. The condenser barrier is arranged as a solid of revolution with concentrically laid condenser layers. It is formed from both ends with inwardly-directed, straight frustums of cones with equally large smallest bases, between which the condenser barrier is formed as a concentric inner, straight circular cylinder.
