Scene 1

[Audio] 1. After arrangement of G-I-S--, nitrogen from G-I-S should be deflated from its compartment.
2.Check the insulator and condition of bolt.
It should be no damaged and scratched on surface of gas barrier.
3. Cleaning the surface of flange, insulator and section of conductor.
4.Use the high duty of vacuum cleaner to clear up inside compartment to avoid any dust & particle which
5. may occur partial discharge..
