Abstract :
The breakdown distribution functions are presented for arrangements with quasi-homogeneous field distribution and the maximum reduction of the electrical strength due to the area effect is determined. Furthermore, the influence of critical defects is discussed with respect to the on-site tests and the operation reliability. It is shown that the operation reliability of GIL can be verified with the test procedures approved for GIS.
