Answer / h s sandhu

Since there is oil in the transformer and with the load increasing the temp of oil increases because of more current flowing in HT/Lt windings .We measure the temp of oil with the max limit st as per Is of the transformer.( 90deg above ambient )

Answer / jithendra

 Transformer oil is a medium for Transformer winding to decrease the winding temperature when load increases simultaneously winding temperature increases, so oil is used & also it is insulated oil.

Answer / rutulsoni

in trasformer there is increase in temprature with increase load.we measured temp of transformer to measured insulation resistance of device.it shoud not excedd above 85 C in oil tank and shoud not exceed above 95 C between winding...is this right? pls give me feed back
