DIPLOMA In ELECTRICAL ENGINEERING DEPARTMENT OF ELECTRICAL ENGINEERING GOVERNMENT POLYTECHNIC COLLEGE, HANUMANGARH Sept A Training Presentation On 132 KV GRID GSS KHAJUWALA,BIKANER Presented to Mr. Anand jain Presented by Prerna Middha 10/1/2019 1

2 COMPONENT OF GSS  Transformer  Instrument  Transformer:-CT,PT,CVT  Wave Trap  Lightning Arrestors  Insulator  Bus-bar  Circuit Breaker(SF6).  Battery Room & Control Panel  Solator  Cable tray & Cable trench

10/1/20193 The assembly of apparatus used to change some characteristic  About GSS  The assembly of apparatus used to change some characteristic  (e.g. voltage, ac to dc, pf. Etc.) of electric supply.  Feeders at 132KV KHAJUWALA  GSS:-132 KV line(1)Incoming  132/33 KV line (6)Outgoing  33/0.4 KV line (1)Outgoing

10/1/20194 TRANSFORMER  A TRANSFORMER IS AN ELECTRICAL DEVICE THAT TRANSFERS ENERGY BETWEEN TWO OR MORE CKT TROUGH ELECTROMAGNETIC INDUCTION. Power transformer Current transformer Potential transformer Capacitance voltage transformer Distribution transformer TRANSFORMER

10/1/20195 Power Transformer

10/1/20196 Potential Transformer A step down instrument Transformer for measurement, control & protection Potential Transformer

10/1/20197 For measurement & Protection purpose. Current TransformerFor measurement & Protection purpose. A step up transformer which step down the current to a known ratio for measurement, control & protection. Digital Metar

10/1/20198 Capacitor voltage transform A capacitor voltage transformer (CVT or CCVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal, for metering or operating a protective relay Capacitor voltage transformer DIGRAM

10/1/20199 Protection for transmission line & GSS from direct strokes Lightning Arrestors Protection for transmission line & GSS from direct strokes

10/1/ A wave trap is a device that allow only a particular frequency to pass through it that it filters the signals coming on to it. So a wave trap is connected between buses and the transmission line which allow only 50 Hz signal to pass through it. A wave trap

10/1/ Lightning arrester Protection for transmission line & GSS from direct strokes

10/1/ Insulator & Bus-bar

10/1/ Circuit Breaker(SF6) Circuit breaker is used for switching during normal and abnormal conditions. Used to Close or Open electrical circuit. It is used to interrupt short circuit currents. It can be operated manually or automatically Circuit Breaker

10/1/ Battery room & Control panel Battery Control panel

10/1/ Isolator A switch which designed to open a circuit under no load

10/1/ Cable tray & Cable trench For purpose of laying cables in ground Provides internal wiring to various part of GSS
