132kv Substation

  1. 1. A visit to 132kv S/S PGI
  2. 2. Single Line Diagram-132/33/11kv Sub-station PGI
  3. 3. 3 incomer from 400/220KV s/s Sarojini Nagar & 1 outgoing 132kv line to Gomti Nagar & Martin purva 132kv incomer incomer outgoing
  4. 4. 132kv incoming lines through Lightning Arrestor & is connected to the Gantry through insulated discs. Disc insulators Lightning Arrestor Incomer gantry Lightning Arrestors Bus bar for all 3 incomer & 1 outgoing line
  5. 5. The line moves ahead passing through polycon insulators & to the circuit breakers (CB) moving ahead to the main bus bar <ul><li>From Gantry the line moves through Capacitive Voltage Transformer (CVT) & Current Transformer (CT) </li></ul>Capacitive Voltage Transformer(CVT) Current Transformer(CT) Polycon Insulator 132KV SF6 CB
  6. 6. <ul><li>The line ,through the isolators is distributed in the s/s through Main bus. </li></ul>Main Bus bar 132kv Bay
  7. 7. 132kv Bay terminating to 20MVA 132/11kv Transformer Isolators Transfer Bus
  8. 8. 40MVA 132/11kv transformer feeding PGI <ul><li>Tendum isolator, used for rectification works to isolate the equipment </li></ul>Transformer Gantry Transformer LA Current Transformer(CT) Tendum Isolator
