Tube Oil Level Gauge Indicator

When the transformer is running, the oil temperature will change with the load and other factors. According to the principle of thermal expansion and contraction, when the oil temperature rises, the volume of the oil will expand, the oil level rises; when the oil temperature falls, the volume of the oil contracts, the oil level falls. Tube oil level gauge can reflect this oil level change caused by oil temperature change in real time, to help operation and maintenance personnel to judge whether the transformer's operating status is normal.
