Oil Filled Transformers

  • Low-cost solution for key incipient fault marker that is easy to install and maintain
  • Operates immersed directly in transformer oil or headspace
  • Continuous hydrogen monitoring reveals potential faults to ensure timely action and avoid downtime
  • Reduced dependence on costly oil sample based DGA diagnostics
  • No membrane, consumables, moving parts or reference gas
