Answer / vels
to determaine the insulation condition if the tan delta
value is higher than 0.7 for a transformer,then oil has to
be tested in all aspects .from the oil results we can under
stand where the insultion is weaks

Answer / sunil guru
tan DELTA test is used to determine the insulation strength of oil
to determine the break down strength,flash point,its fire point,and also to identify the moisture content of the oil
their is certain fix value for all above said......
if the oil colour changes then it may be said that it may not be suitable for large time......

Answer / pati
Ionic traces can effect the Tan delta of insulating oil
like transformer oil.The amount of charge particle directly
proportional to the electrical properties, hence tan-delta
test essencial for Transformer oil.
