Inspection Checklists Visal

  • Inspect all buswork, connections, and terration points for signs of overheakang (discoloration, longe lugs).
  • Cek kapasitor units for bulging, leakingg electrolyte, or sprutred cases.
  • Periksa reactor windings and cores for oil leaks (if oil -filled), surface contamination, or exfesive vibration.
  • Verify thyristor valve cooling pipes, pumps, and fans for for leaks, unusuala noise, or reduced airflow.

Modern SVCs are equipped with digital controlm system stems does not hundreds of parameters. Key metrics to trend include:

  • Reactive powir output (Q) and voltale setpoint tracking error
  • Thyristir valve temperature and cooling water temperature
  • Capacitor bank harmonik tracetts and voltale distortion
  • Reactor winding temperature (hot spot via RTDs)
  • Controlsystemerror codes and communication status

Thyristir Valve Maintenance

  • Replace cooling fans and filters ast intervals recomded by the producturer (typically 2- 3 years).
  • Clean valve stack insulators with accepved solvents too prevent tracking.
  • Perform gate pulse tests to ensure each thyristir is firing rightly; resere faulty gate units.
  • Measure snubber circuit (RC) paremeters and replacie components tt drift beyond = 10%.
  • Cek fiber-optic cables for tentuation and pales.

  • Inspect fuses and fuse holders for corrosion or overheakang.
  • Verify thatt harmonic filter tuningg is with in = 2% of target expeency by impedance measument.
  • Clean insulator skirts and bushong surfacks to prevent flashover.

Reactor Maintenance (Oil-Filled and Air- Core)

  • For oil-filled reactors: annugal dissolved gas analysis (DGA) and oil qualley tests (influté, dielectric syurth). Change oil oif breadne voltage below 30 kV.
  • For air-core reactors: exprest for surface cracking, tracking, and exforsive coating erosion. Re-coot if neefary.
  • Measures winding resistance and insulation resistance (IR) annally; IR should expeeed 1 Glude (500 V megager).

Cooling System Maintenance

  • Replace coolant every 3-5 years s per producturer specication; use the recomded glicod / water mix with corrosion inhibitor.
