2. LIGHTNING ARRESTER device which provides protection
Lightning arrester is a protective
device which provides protection
against high voltage from lightning.
A Lightning arrester has two
terminal viz a high voltage terminal
and a ground terminal.
It is used only for overhead line.

3. Bus bar Types of bus bar Main Bus Bar Auxiliary Bus Bar
A Bus bar is a conducting bar that carries
heavy currents to supply several electric
circuits.
Bus bar is made from ‘Cu’ and ‘Al’.
Types of bus bar
Main Bus Bar
Auxiliary Bus Bar
One Bus Bar is Main Bus Bar and another is Auxiliary Bus Bar.

4. TRANSFORMER TRANSFORMER USED IN GSS
A transformer is a static device that transfers electrical energy from one electrical circuit to another electrical circuit by means of a common magnetic Circuit.
TRANSFORMER USED IN GSS
POWER TRANSFORMER
CURRENT TRANSFORMER
POTENTIAL TRANSFORMER

5. Power transformer MAIN PARTS OF POWER TRANSFORMER-
To step-down the voltage and transfer power from one A.C voltage to another A.C Voltage at same frequency.
MAIN PARTS OF POWER TRANSFORMER-
Winding(H.V winding , I.V winding)
Core
Tap changer
Conservator Tank
Buchholz Relay
Oil Temperature Indicator
Winding Temperature Indicator
Cooling fans

6. Current transformer
Current Transformer is an instrument transformer used to protection & Metering of high values of current.
Current Transformer:- A C.T is used to step down current for measurement, control and protection.

7. Potential transformer
Potential Transformer:- Potential Transformer are Instrument Transformer. A P.T is used to step down voltage for measurement, control and protection.

8. TRANSFORMER COOLING ONAN Oil natural air natural ONAF

9. ISOLATOR
It isolates the devices from live line when there is a maintenance. It operates when there is no load.
It is also used to change bus bar line from main to reserve or vice-versa.

10. CIRCUIT BREAKER TYPES OF CIRCUIT BREAKER-
A Circuit Breaker is an automatically or manually operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit.
TYPES OF CIRCUIT BREAKER-
which is used in 132kv GSS Behror
SF6 Circuit Breakers
Vacuum Circuit Breakers

11. SF6 C.B.

12. INSULATORS
In order to avoid current leakage to the Earth through the supporting structure, insulators are used in the conductor of overhead transmission lines

13. POWER LINE CARRIER COMMUNICATION
For exchange of data and transfer message between grid substation , Voice communication is necessary. For this purpose high frequency Carrier current is transmitted on same transmission line on which power is transmitted.
Hence such communication is called-
“POWER LINE CARRIER COMMUNICATION”. .

14. CAPACITOR BANK
Capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses.

15. CONTROL ROOM
To remote control of power switch gear requires the provision of suitable control plates located at a suitable point remote from immediate vicinity of CB’s  and other equipment.

16. BATTERY ROOM & CHARGER
In a GSS, Separate dc supply is maintained for signaling remote position control, alarm circuit etc. There is a battery room which has 55 batteries of 2 volt.

17. At last I would say... Energy Saved Is Energy Produced...!
Thank you
