  Electric Arc-Induced Pyrolysis of Transformer Oil: A Pathway to Combustible Gas Generation, Fireball Formation, and the Challenge of Visual Scale Perception in Night-Time Incidents
  Author(s): Miltiadis Karazoupis*
  
  Power transformers are critical components in electrical grids, and their operational integrity is paramount. The mineral oil used within these transformers serves as both an insulator and a coolant. However, internal electrical faults, particularly high-energy arcing, can subject this oil to extreme thermal stress. This article investigates the phenomenon of pyrolysis in transformer oil initiated by electric arcs, typically resulting from fault conditions with voltages such as 25,000 Volts or higher within the equipment's operational context. It explores the mechanisms by which arc-induced high temperatures lead to the decomposition of insulating oil into various combustible gases, primarily hydrogen, acetylene, methane, and ethylene. The rapid generation and accumulation of these gases can cause a significant pressure rise within the transformer tank, potentially leading to tank.. Read More»
