what is the significance of tan delta testing?explain the
theory?
Answer Posted / manish yadav
tan angle is the ratio of resistance current and
capacitive current ..it is used to estimate the life of
insulation by comparing periodical tandelta value of the
same insulation..pure insulation has only capacitive
current but with the insulation deteriorationor cavity
formation(may occur due ambient condition temp or cont.
over current flow) resistance is added hence resistive
current increase wich leads to increase in tandelta value..
