  1. 1. A PRESENTATION ON Submitted To:- Mr. Sanjeev Kumar Rajoria Electrical Dept. 132 KV G.S.S. (SITAPURA) Submitted By:- Mirza Sarmad Baig 13EGCEE057 Department Of Electrical Engineering GLOBAL COLLEGE OF TECHNOLOGY 2013-2017
  2. 2. RRVPNL(An Organization) ▪ Rajasthan Rajya Vidyut Prasaran Nigam Limited (RVPN) a company under the Companies Act, 1956 and its Registered Office is at VIDYUT BHAWAN, JYOTI NAGAR, JAIPUR- 302005 has been established on 19 July, 2000 by Govt. of Rajasthan. ▪ 132KV GSS Sitapura(Jaipur) come under the company of RRVPNL. Its aim is to provide reliable electric transmission service to the customers.
  3. 3. Contents:- ▪An Overview ▪Working ▪Components ▪Conclusion
  4. 4. OVERVIEW G.S.S. – GRID SUB STATION • WHAT • HOW
  5. 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 • Distribution system 132KV GSS Sitapura Yard 33KV GSS Sitapura yard
  6. 6. STRUCTURE OF G.S.S.(SITAPURA) INCOMING LINES 132 kV INDRA GANDHI NAGAR 132KV SANGANER OUTGOING LINES 33 KV NRI 33 KV SITAPURA 33 KV PRATAP NAGR 33 KV MICO 33 KV TIJARIA 33 KV STONE MART ….. Many more.

  9. 9. CURRENT TRANSFORMER POTENTIAL TRANSFORMER RATING (1000/1) 132KV (250/5) 33KV CURRENT TRANSFORMER POTENTIAL TRANSFORMER RATING FOR 33 KV BAY
  10. 10. LIGHTINING ARRESTER
  11. 11. CAPACITIVE VOLTAGE TRANSFORMER CAPACITIVE VOLTAGE TRANSFORMER SPECIFICATIONS INSULATION LEVEL : 460KV PRIMARY VOLTAGE : 132/1.732KV SECONDARY VOLTAGE : 33/1.732KV WEIGHT : 850 KG Transformer used to step down extra high voltage and supply low voltage
  12. 12. CIRCUIT BREAKER • ELECTRICAL SWITCH • PROTECTION PURPOSE SF6 C.B. SPECIFICATIONS RATED VOLTAGE : 145 KV RATED CURRENT : 2000 A RATED SHORT CIRCUIT CURRENT TIME DURATION : 3 sec RATED SF6 GAS PRESSURE : 7 bar RATED AIR PRESSURRE : 20 bar MAXIMUM WEIGHT : 1750 Kg
  13. 13. TYPES OF CIRCUIT BREAKER • AIR BLAST CIRCUIT BREAKER • OIL CIRCUIT BREAKER • SF6 CIRCUIT BREAKER • VACCUM CIRCUIT BREAKER
  14. 14. • High dielectric strength • Unique arc quenching ability • Excellent thermal stability • Good thermal conductivity ADVANTAGES OF SF6 WORKING
  15. 15. ISOLATORS • SWITCH • ISOLATE CIRCUIT SPECIFICATIONS 145 KV, 800A
  16. 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. Trips circuit breaker when fault is detected CIRCUIT
  17. 17. RELAY
  18. 18. RELAY
  19. 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 (POWER LINE CARRIER COMMUNICATION)
  20. 20. WAVE TRAP • TRAPS FREQUENCY OF DESIRED LEVEL FOR COMMUNICATION
  21. 21. BUS BARS BUS CARRY HEAVY CURRENT PANTHER CONDUCTORS ZEBRA CONDUCTORS FOR 132KV.
  22. 22. CAPACITOR BANKS • Improve the quality of electrical systems. • Make the operations more efficient. • Reduce line losses.
  23. 23. BATTERY ROOM • 55 BATTERIES OF 2V. • FOR EXTERNAL CIRCUITS.
  24. 24. CONTROL ROOM • Increase reliability and performance of electrical protection. • Remote switching and advanced supervisory control. • Intelligent load shedding system.
  25. 25. SINGLE LINE DIAGRAM OF G.S.S. (Working)
  26. 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.
