What are the requirements for transformer oil temperature sensors?

Transformer oil temperature sensors must meet specific requirements to ensure accurate monitoring and protection of the transformer. They should have a temperature range suitable for transformer operation, typically from -40°C to 120°C. The sensors must be resistant to oil and moisture, ensuring durability and reliability. Additionally, they should provide fast response times and be compatible with the transformer’s control system for real-time data transmission. Calibration and accuracy standards are also critical for effective temperature management.
