how to read transformer oil level gauge?

To read a transformer oil level gauge, first locate the gauge, typically mounted on the transformer tank. The gauge will have a scale indicating oil levels, often marked with “Low,” “Normal,” and “High” indicators. Ensure the transformer is not under load when checking. Observe the position of the float or pointer against the scale; a reading within the “Normal” range indicates adequate oil levels for cooling and insulation. Regular monitoring is essential for transformer health.
