Sažetak

Pluggable bushings offer numerous advantages over conventional bushings, but with the same performance characteristics: simple and much faster to install, they do not require any oil or gas work on site in the substation; they are solid-insulated, explosion-proof, and can be replaced and used over again at any time. Plus they are signifcantly shorter, requiring considerably less space inside a transformer. Of course, the same is true for use in gas-insulated switchgear (GIS). Demand for pluggable bushings, which were developed around twenty years ago mainly for testing and measurement purposes, has been steadily growing in recent years – together with their scope of applications. Given the changing grid structure and rising challenges associated with the energy transition, grid operators worldwide recognise the advantages of pluggable bushings in terms of greater planning flexibility and the future flexible use of transformers
