The conductivity of transformer oil is a critical parameter that indicates its ability to insulate and protect electrical equipment. Typically, transformer oil has a very low conductivity, usually measured in picoSiemens per meter (pS/m), often ranging from 0.1 to 1.0 pS/m in well-maintained oils. The lower the conductivity, the better the oil insulates and separates conductive contaminants, which is essential for minimizing leakage currents and ensuring the longevity of transformers. Factors such as contamination, temperature, and the aging of the oil can significantly affect transformer oil conductivity, making regular monitoring and maintenance vital to ensure optimal performance and reliability.
