Biodegradable ester-based oils are gaining popularity due to their high fire safety profile and lower toxicity compared to traditional mineral oils. This highly refined mineral oil creates a stable dielectric medium that prevents electrical discharge within transformers.
Transformer Oil Diagnostic Monitoring: Key Tests and Maintenance Strategies
Standard tests include breakdown voltage measurement, interfacial tension, and pour point determination to ensure compliance with IEEE C57. Overheating due to overloading or cooling system malfunctions accelerates acid formation, necessitating immediate filtration and neutralization procedures.
Simultaneously, it acts as a heat transfer fluid, carrying thermal energy away from hot spots in windings and the core to cooling radiators. Primary Functions in Power Equipment Insulation remains the primary function, maintaining dielectric strength between conductive windings and core laminations.
