  1. 1. 132/33KV SUBSTATION RAJA KA TALAB VARANASI SUBMITED BY- - JAGDEESH KUMAR MAURYA 1342220904 E.E. 4th YEAR BANSAL INSTITUTE OF ENGINEERING & TECHNOLOGY LUCKNOW SUBMITED TO - Mr. B.R. SINGH HOD OF E.E
  2. 2. 132KV INCOMING  132KV INCOMING MANDUADIH, GAJOKHAR & AUARI 132KV INCOMING
  3. 3. 132KV INCOMING MANDUADHI
  4. 4. LIGHTNING ARRESTORS LIGHTNING ARRESTORS  It is connected between line and earth so diverts the incoming high voltage wave to earth.  When a lightning surge travels along the power line to the arrester, the current from the surge is diverted through the arrestor in most cases to
  5. 5. CURRENT TRANSFORMERS [C.T.] 400/200/100/1A (BHEL) CURRENT TRANSFORMERS  A Current transformer (CT) is used for measurement of alternating currents.  A Current transformer is 400amp to 1amp step up T/F .  CT is connected in series with circuit.
  6. 6. BUS ISOLATOR BUS ISOLATOR  The line through the Bus isolator is distributed in the substation main bus.  It is disconnects the circuit from the main power supply.  Open the isolator on no load .
  7. 7. VacuumCIRCUITBREAKERS (CGL) CIRCUIT BREAKERS  Circuit beaker used to protect the equipment by opening the circuit for over current and over voltage.  A circuit breaker which can open or close a circuit under normal as well
  8. 8. RELAY  When a short circuit occurs at any point on the transmission line the current flowing in the increases to the enormous value. This result in a heavy current flow through the relay coil, causing the to operate by closing its contacts
  9. 9. Main bus-bar MAIN BUS BAR  ACSR moose conductor use in main bus bar and consist of a 54 wires in aluminium and 7wires in steel
  10. 10. POTENTIAL TRANSFORMERS [P.T.] POTENTIAL TRANSFORMERS  A Potential transformer is used for measurement of voltage.  PT is used in power system to step down extra high voltage and provide a low voltage, for measurement or to operate a protective relay
  11. 11. TRANSFER BUS TRANSFER BUS  It is used in ACSR conductor.  It is transfer bus through supply in different -2 transformer
  12. 12. SF6 CIRCUIIT BREAKERS (ABB) SF6 CIRCUIT BREAKERS  Sulfur hexafluoride (sf6) gas is used as the arc quenching Medium.  The sf6 is an electronegative gas and has a strong tendency to absorb free electrons.  CB has developed for voltage 115kv to 230kv.
  13. 13. Vacuum circuit breaker VACUUM CB  Vacuum circuit breakers are circuit breakers which are used to protect medium and high voltage circuits from dangerous electrical situations
  14. 14. LINE ISOLATORS LINE ISOLATORS  Line isolator is line side isolator
  15. 15. CURRENT TRANSFORMERS [C.T.] 400/200/100/1a (BHEL) CURRENT TRANSFORMERS  A Current transformer (CT) is used for measurement of alternating currents.  A Current transformer is 400amp to 1amp step up T/F .  CT is connected in series with circuit.

  17. 17. HV SIDE 63MVA 132/33 STAR- STAR T/F CONSERVATOR TANK BUCHHOLZ’S RELAY SILICA GEL 132/33 ADITYA TRANSFORMER COOLING FINS TAP CHANGER SWITCH NUTRAL TERMINEL  Transformer is a heart of substations. These are used to reduce the
  18. 18. LIGHTNING ARRESTORS CIRCUIT BREAKERSCURRENT TRANSFORMERS[C.T.] 33kv busbar 33KV BUSBAR  33kv bus bar in connected in parallel operation in two transformer. one is 40MVA and 63MVA
  19. 19.  33KV BUS WITH PARALLEL OPErATION IN 40MVA & 63MVA 33KV PIN INSULATOR PARALLEL OPerATION
  20. 20. 40 MVA 132/33 TRANSFORMER LIGHTNING ARRESTORS C.T. LIGHTNING ARRESTORS 132/33 ,40MVA TRANSFORMER COOLING FANS  132/33, 40MVA, BHARAT BIJALI transformer step down transformer.  It is connected in parallel operation.  It is load share in parallel.
  21. 21. 33KV OUTGOING VACUUM CB 33 KV OUTGOING  33kv 7 outgoing ROHANIA , ADALPURA , LOHTA, SEWAPURI, JAMUA , THATRA and JAKHANI.
  22. 22. 10MVA 33/11 TRANSFORMERS 33/11 TRANSFORMERS  33/11 STEP DOWN TRANSFORMER . wall
  23. 23. CAPACITOR BANK CAPACITOR BANK  The load on the power system is varying being high during morning and low in evening which increases the load current. This result in the decreased power factor.  In order to improve the power factor come device taking leading power should be connected in parallel with load . One of device can be
