What are the technical aspects of transformer oil level measurement?

Transformer oil level measurement involves monitoring the oil level within the tank to ensure proper insulation and cooling. Key technical aspects include the use of float switches or capacitive level sensors for accurate readings, the calibration of these devices to account for temperature variations, and the integration of alarms for low oil levels. Additionally, maintaining proper oil level is crucial for preventing overheating and ensuring the longevity of the transformer. Regular maintenance checks are also essential for reliable operation.
