Answer Posted / pradhyumn
OTI stands for Oil Temperature Indicator and WTI stands for
Winding Temperature Indicator. They are used for
Transformer protection.The temperature of winding increases
as the load increases. Oil is used as coolant for the
winding so as winding heats up oil temp. rises as well.
The life of transformer depends on insulating material
between the windings so it is important to check and
control the temp. OTI and WTI are thus used for alarm or
tripping of the transformers.
