Winding Temperature Indicator

Listing ID #1434400

Winding temperature indicator : the winding is the component with highest temperature within the transformer and, above all, the one subject to the fastest temperature increase as the load increases. Thus to have total control of the temperature parameter within transformer, the temperature of the winding as well as top oil, must be measured. An indirect system is used to measure winding temperature, since it is dangerous to place a sensor close to winding due to the high voltage. The indirect measurement is done by means of a built-in thermal image.
