| 1.00Servicing & overhauling of single pole, triple pole diverter switch of OLTC of 132/33 KV , 220/132 KV & 400/132kV Power Transformer/ ICTs. Detailed scope of work is given bellow- 1. Perform the Pre Overhauling Test: Continuity test and Ratio Test. 2. Check OLTC manual operation, raise and Lower side 3. Drain the oil of OLTC diverter chamber and OLTC conservator tank in clean and moisture free empty barrel. 4. Open the top Cover of OLTC after then, remove the diverter switch assembly from diverter chamber. 5. Check and clean the carbon deposition in the OLTC Diverter switch chamber with the help of pressurised power transformer oil by oil filtration machine. 6. Cleaning of moving & fixed contacts of diverters switch and diverter chamber with the help of hot transformer oil. 7. Check and correct the diverter operation without selected load (disconnecting selected load). 8. Check the value of transition (shunt) resistance in the resistance basket assembly. 9. Check and correct the looseness and tightness of the resistance basket assembly connections. 10. Replace the Required Material like Contacts, Top Oil seal or O ring including other consumable items & after that fill the OLTC with oil through filter machine after checking BDV of oil. (BDV should be minimum 60 KV). 11. Re-assembly of diverter switch after cleaning of diverter chamber & then check the Oil level in Conservator tank. 12. Release the air from the OLTC chamber by changing the taps of the OLTC manually, 13. Check the looseness and tightness of the drive mechanism of OLTC, 14. Check and correct, all the gear box and shaft alignment (Greasing of gear box). 15. Check and test all the Electrical Contactors and relays in Drive mechanism (MCB's, Motor Operation and Raise/Lower Operation) 16. Check and correct all the electrical connections of the diverter mechanism bas and correct electrical Operation through Local control & Remote control. 17. Check the connections & Signals of RTCC panels related to OLTC (TPI, raise, lower & Hooters) & replace the same if required. 18. Perform Post Overhauling Test: Continuity test, Ratio Test. | ||||||
