What is the maximum operating temperature for transformer oil?

The maximum operating temperature for transformer oil typically ranges from 90°C to 110°C (194°F to 230°F), depending on the specific type of oil and the design of the transformer. Exceeding this temperature can lead to accelerated aging of the oil, reduced insulation effectiveness, and potential transformer failure. It is crucial to monitor and maintain oil temperatures within these limits to ensure optimal performance and longevity of the transformer.
