4. OVERVIEW
G.S.S. – GRID SUB STATION
• WHAT
• HOW

5. WHAT IS G.S.S.?
• A substation is a large installation of transformers to change voltage levels
between high transmission voltages and lower distribution voltages, or at
the interconnection of two different transmission voltages.
• Transmission System

16. RELAY
Relays are used where it is necessary to control a circuit by a separate
low-power signal, or where several circuits must be controlled by one
signal.

19. FOR INFORMATION TRANSFER THROUGH CONDUCTOR.
FOR ELECTRIC POWER TRANSMISSION.
ADVANTAGES:-
• No separate power are require for transmission purpose.
• They have high mechanical strength.
• Provide shortest distance through power stations.
DISADVANTAGES:-
• Proper care has to be taken to guard carrier equipment.
• Noise introduced in power line is much more than the telephone lines.
PLCC

22. CAPACITOR BANKS
• Improve the quality of electrical systems.
• Make the operations more efficient.
• Reduce line losses.

23. BATTERY ROOM
• 55 BATTERIES OF 2V.
• FOR EXTERNAL CIRCUITS.

24. CONTROL ROOM
• Increase reliability and performance of electrical protection.
• Remote switching and advanced supervisory control.
• Intelligent load shedding system.

26. CONCLUSION
The training at substation was
very helpful. It has increased
my theoretical knowledge about
power transmission and
distribution.
Maintenance and protection of
various circuit equipment's.
