Answer / hardik vyas
TAN Delta test gives you the condition of the insulation
and also it helps in predicting that how long this
equipment can be in service. In short it gives you the
detoriation rate of insulation so you can predict the
remaining useful period of perticular euipment.

Answer / ashish barak
when insulation is perfect , there is only capacitive
current and angle between current and voltage is 90 degree.
as insulation degrades with time there is a flow of
resitive current also. the angle between capacitave and
resultant current(sum of resitive current and capacitive
current)is this "delta" angle.
as it keeps on increasing it indicates winding is
deterioating
