Oil Temperature Indicators

Oil Temperature Indicator is a small compact electrical device which helps to measure the top oil temperature. It is mechanical indicating device whichmeasures the heat level with the help of sensing bulb dippedin the pocket by using liquid expansion in the bulb through a capillary tube to the operating mechanism is fixed with a needle which shows the temperature. Oil Temperature Indicator helps to control and protect the transformers.It works when the volume of the liquid changes this movement is transmitted to the pointer in temperature indicator. This Device is used to measure the top oil temperature and OTI is also used for protection of the transformer.
