6. Potential Transformer
A step down instrument Transformer for measurement, control & protection
Potential Transformer

7. For measurement & Protection purpose.
Current Transformer
For measurement & Protection purpose.
A step up transformer which step down the current to a known ratio for measurement, control & protection.

8. CVT For measurement the Voltage. For Protection system.
For communication system.

9. To prevent high frequency signals from entering other zones.
Wave Trap
To prevent high frequency signals from entering other zones.

10. Protection for transmission line & GSS from direct strokes
Lightning Arrestors
Protection for transmission line & GSS from direct strokes

11. Insulator & Bus-bar

12. Circuit Breaker(SF6)
Circuit breaker is used for switching during normal and abnormal conditions.
Used to Close or Open electrical circuit.
It is used to interrupt short circuit currents.
It can be operated manually or automatically

13. Battery room & Control panel

14. Isolator
A switch which designed to open a circuit under no load

15. Cable tray & Cable trench
For purpose of laying cables in ground
Provides internal wiring to various part of GSS
