The role of the transformer oil level meter

Transformer oil level meter can intuitively display the height position of the oil level in the transformer tank or oil storage cabinet. For example, the tube oil level meter through the buoy indication device, can show the lower part of the box cover within a certain range of the specific oil level, let the operation and maintenance personnel clearly understand the oil level situation.

Transformer oil temperature will change with the load and ambient temperature and other factors, oil temperature changes will lead to oil volume thermal expansion and contraction, so that the oil level changes accordingly. Through the oil level meter to observe the rise and fall of the oil level, you can indirectly understand the transformer oil temperature trend.
