How does the dielectric strength of silicone oil affect transformer operation?

The dielectric strength of silicone oil is a measure of its ability to withstand electric stress without breaking down. High dielectric strength ensures effective insulation between the transformer’s conductive components, preventing electrical discharges and short circuits. If the dielectric strength decreases due to contamination or degradation, it can lead to insulation failure, resulting in transformer malfunctions or catastrophic failures. Maintaining high dielectric strength is essential for the safe and efficient operation of transformers.
