tan delta test means we test the healthiness dielectric strength of bushing present condition,at this same time we maser capacitance also .
conductor surrounding oil impregnated paper is there it is terminated at test point,it is equivalent to capacitance .Healthy capacitor current and by 90 degrees.during deterioration time some resistance added,resultant is leakage current,it is checked by we conducting tan delta.
this resultant values compared to manufacturer reports and factory test reports.
tan delta value always in percentage.
Allowable value for tan delta test is 0.8 %
tan delta also called loss angle.
test details : we are using megger kit,it is combination of control unit and transformer unit.
we are applying 2kv 5kv 10kv
our kit capacity is 12kv. you have one dought here ,Wye we are applying higher voltages for higher Transformers bushings,
you remember one thing here we increase voltage ,will not increase
loss factor (tan delta)
