Transformer Oil Analysis
About Transformer Oil Analysis • Transformer oils are subject to electrical and mechanical stresses while a transformer or other electrical distribution equipment is in operation. • The analysis of insulating oils provides information about the oil, but also enables the detection of other possible problems, including arcing, aging insulating paper and other latent faults and is an indispensable part of a cost-efficient electrical maintenance program. • Though the failure risk of a transformer and other oil-filled electrical equipment is small, when failures occur, they inevitably lead to high repair costs, long downtime and possible safety risks. By accurately monitoring the condition of the oil, suddenly occurring faults can be discovered in time and outages can potentially be avoided.
Properties of Transformer or Insulating Oil : • Some specific parameters of transformer or insulating oil should be considered to determine the serviceability of that oil. • Physical Parameters – Colour and Appearance, Density, Inter Facial Tension, Viscosity, Flash Point and Pour Point. • Chemical Parameters - Water Content, Corrosive Sulphur, Acidity, Sludge Content. • Electrical Parameters – Dielectric Strength, Specific Resistance, Dielectric Dissipation Factor. • Dissolved gas analysis • Furan analysis • PCB analysis
The Furan and DGA tests are specifically not for determining the quality of transformer oil, but for determining any abnormalities in the internal windings of the transformer or the paper insulation of the transformer, which cannot be otherwise detected without a complete overhaul of the transformer. Dissolved Gas Analysis or DGA of Transformer Oil Dissolved gas analysis determines the concentrations of certain gases in the oil such as nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrogen, methane, ethane, ethylene and acetylene The concentrations and relative ratios of these gases can be used to diagnose certain operational problems with the transformer, which may or may not be associated with a change in a physical or chemical property of the insulating oil.
