Inductive Voltage Transformers
SF6 insulated Inductive Voltage Transformers

Main Features

  • Explosion proofed design by the compressible insulation medium SF6 and rupture disc
  • Excellent seismic performance
  • Cast aluminuim housing
  • Ferroresonance free design with or without external damping device depending of client substation layout
  • Essentially unaffected by external stray magnetic fields
  • Optimal field grading accomplished by a fine condenser grading system
  • Stable accuracy over a long period of time
  • Suitable for line discharging
  • Maintenance free
  • No insulation ageing
  • Remote supervision of insulation condition by monitoring internal gas density

 

Type TVG

  • Head design from 72.5 to 245 kV
  • Tank design for 420 kV
  • Optimized high voltage coil assures identical electric stresses under both transient and steady state conditions
  • SF6  insulation
  • Porcelain or Composite insulator
  • Essentially unaffected by external stray magnetic fields
  • Wide ferroresonance-free design without the use of an external damping device
  • Suitable for line-discharging
