Overview

Experimental study demonstrates altered fault gas generation by dissolved oxygen in biodegradable insulating liquids, suggesting necessary revisions to standard diagnostic frameworks.

Key Points

  • To evaluate how varying concentrations of dissolved oxygen influence fault gas formation in biodegradable insulating liquids under electrical and thermal stress.
  • Systematically altered initial dissolved oxygen levels in two biodegradable liquids: bio-based hydrocarbons and synthetic esters.
  • Subjected samples to laboratory-simulated electrical arcing and localized thermal heating cycles.
  • Analyzed post-fault gas concentrations using standard dissolved gas analysis (DGA) diagnostic tools, including Duval's triangle and pentagon methods.
  • Identified a strong correlation between dissolved oxygen concentrations and the volume and composition of generated fault gases.
  • Demonstrated that oxygen-induced gas alterations can cause conventional DGA models to misinterpret fault types in biodegradable insulating fluids.
