  3. 3. INTRODUCTION  Uttar Pradesh Power Corporation Limited (UPPCL) is the company responsible for electricity transmission and distribution within the Indian state of Uttar Pradesh .  The creation of Uttar Pradesh Power Corporation Ltd. (UPPCL) on January 14, 2000.  UPPCL Barahua 220 KV substation was established in 1979.  UPPCL Barahua substation is basically contains two substation one of 220/132 KV & other one of 132/33 KV.

  7. 7. SUB-STATION  A substation is a part of an electrical generation, transmission, and distribution system.  The assembly of apparatus used to change some characteristics (e.g. Voltage ac to dc freq. p.f. etc) of electric supply is called sub-station.  Substations transform voltage from high to low, or the reverse, or perform any of several other important functions.  Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

  9. 9. TYPES OF SUB-STATION  Substations may be described by their voltage class, their applications within the power system. 1. Transmission substation 2. Distribution substation 3. Converter substation
  10. 10. SELECTION OF SITE  The site chosen should be as near to the load center as possible.  It should be easily approachable by road or rail for transportation of equipments.  Land should be fairly leveled to minimize development cost.  Source of water should be as near to the site as possible. This is because water is required for various construction activities (especially civil works), earthing and for drinking purposes etc.  The sub-station site should be as near to the town / city but should be clear of public places, aerodromes, and Military / police installations.
  11. 11. COMPONENT OF S/S The equipment required for a transformer Sub-Station depends upon the type of Sub-Station –  Bus-bar  Insulators  Circuit breaker  Instrument Transformer  Current Transformer  Voltage Transformer  Transformer  Lightening arrestors  Wave trap
  12. 12.  Bus-bar:  The bus is a line in which the incoming feeders come into and get into the instruments for further step up or step down.  The first bus is used for putting the incoming feeders in LA single line.  Insulators:  The insulator serves two purpose – 1. they support the conductor (or bus bar) 2. confine the current to the conductor.  The most commonly used material for the manufactures of insulators is porcelain.
  13. 13.  Transformer:  Transformer is a static machine, which transform the potential of alternating current at same frequency.  It means the transformer transforms the low voltage into high voltage and high voltage into low voltage at same frequency.  It works on the principle of static induction principle.

  14. 14. TYPES OF TRANSFORMER:  Power Transformer  Instrument Transformer  Auto Transformer 1. POWER TRANSFORMER: Fig 3: 132/33 KV 40 MVA transformer at barahuwa sub-station
  15. 15. 2. INSTRUMENT TRANSFORMER: There are two types of instrument transformer-  Current T/f  Potential T/f  CVT 1. Current Transformer:  A current transformer is essentially a step-down transformer which steps-down the current in a known ratio.  Current transformers are basically used to take the readings of the currents entering the substation.
  16. 16. Fig.4. Current Transformer
  17. 17. 2. Potential Transformer:  It is essentially a step – down transformer and step down the voltage in known ratio. Fig.5. Potential Transformer ( Voltage Transformer )
  18. 18. 3. C V T:  A capacitor voltage transformer (CVT ) is a transformer used in power systems to step-down extra high voltage signals .  It provide low voltage signals either for measurement or to operate a protective relay.  Circuit breaker:  A circuit breaker is an equipment, which can open or close a circuit under normal as well as fault condition.  These circuit breaker breaks for a fault which can damage other instrument in the station.  It is so designed that it can be operated manually (or by remote control) under normal conditions and automatically under fault condition.

  22. 22. CONCLUSION  The three wings of electrical system viz. generation, transmission and distribution are connected to each other and that too very perfectly.  Effective voltage control  Reliable supply by feeding the network at various points  Fault analysis improvement in respective field  Establishment of economic load distribution
