Posted by The order consists of switch gears of type 8 ZX0 GIS. Each switch gear consists of 8 panels: 2x 22.9KV and 6x 7.5KV. This results in total 4x 22.9KV and 12x 7.5KV. On each panel, the following list of tests has been performed:
1. Dielectric test on the main circuit ( IEC 62271-200, cl. 7.1)
2. Partial discharge test ( IEC 62271-200, cl. 7.101 and Annex B )
3. Test on auxiliary and control circuits ( IEC 62271-200, cl. 7.2 )
4. Measurement of the resistance of the main circuit ( IEC 62271-200, cl. 7.3 )
5. Mechanical operation tests (IEC 62271-200, cl. 7.102)
6. Electrical function test / Design and visual checks ( IEC 62271-200, cl. 7.104 and 7.5 )
