General disconnecting switch allows the scope of operations

1. normal pull transformer and arrester.

2. pull 220kV buses without load.

3. pull power when there is no ground fault of transformer neutral point.

4. close the switches or bypass current isolating switch is closed.

5. outdoor vertical-type triple isolation switch, voltage of 220kV and above does not exceed 2A of excitation current no-load transformer and capacitor current does not exceed 5A line.

6.10kV Outdoor triple isolation switch does not exceed 15A load current.

7.10kV disconnector zipping up to 70A, loops of circulating current.
