The operating temperature range for transformer oil typically spans from -30°C to 100°C (-22°F to 212°F). However, for optimal performance and longevity, it is recommended to maintain the temperature between 20°C and 80°C (68°F to 176°F). Exceeding these limits can lead to accelerated aging of the oil and insulation materials, potentially compromising the transformer’s reliability and efficiency. Regular monitoring of oil temperature is essential for safe operation.
