What methods are used in cable oil analysis and what information do they provide?

Methods include:

Dielectric Strength Testing: Measures the maximum voltage the oil can withstand without breaking down.
Moisture Analysis: Determines water content, which affects insulating properties.
Acidity Testing: Indicates oxidation levels and the presence of corrosive compounds.
Dissolved Gas Analysis (DGA): Detects gases formed from thermal or electrical faults.
Particle Count: Assesses the level of particulate contamination.
These analyses provide insights into the oil’s condition, identifying potential risks to cable performance.
