Each of the fault result in thermal degradation of the oil
either alone or in combination with paper insulation. This
gives rise to the evaluation of various hydrocarbon gases,
hydrogen and oxides of carbon, in quantities depending on
the type of fault.

Heavy current arcing is characterized by the evolution of
significant quantities of hydrogen and acetylene (C2H2). If
the arcing also involves paper insulation, the oxide of
carbon will also be present.

Partial discharge usually results in evolution of hydrogen
and lower order hydrocarbons.

Localized heating or hot spot gives rise to methane and
ethane in appreciable amount.

Prolonged overloading or impaired heat transfer can cause
CO and CO2 to be generated due overheating paper
insulation.

an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly
