Temperature monitoring of power transformer winding

The life time of the transformer is predetermined by the temperature to which has been exposed for a long time the winding insulation. Temperature affects its mechanical strength. Insulation paper which is exposed by the long temperature of oil and by vibration becomes too brittle and is unable to withstand short-circuit forces or even the normal vibrations and this situation in practice means not only the end of insulation life time, but also transformer life time. Therefore temperature monitoring is essential for each transformer operator or owner and the only way how to make a direct measurement of winding temperature is fibre optic sensor.
