Answer Posted / a.r.shah
Tan Delta is an effective tool in determining the
insulation condition of power cables using a VLF-TD System
Tan Delta measures the resistive component of a cable
system; a perfect cable is all capacitance and has no
resistance. The resistive component is caused by voids in
the insulation, electrical trees, water trees etc. The
resistive element causes the current not to lead the
voltage by 90° (something less) This is difference in angle
(less than 1° ) is the loss angle. The tangent of this loss
angle is the Tan Delta / or the tangent of the loss angle.
