Measurement of the tangent of the dielectric loss angle of insulation is performed by the Schering bridge at frequency of 50 Hz.
Higher value for the loss angle indicates a high deg- ree of contamination.

The complement of angle between voltage and current vectors is called dielectric loss of angle [delta] or dielectric loss angle.
The dependence of the storage modulus (E') and the loss angle tangent (tan 6) on temperature for SF/PU blend fibrous membranes are shown in Fig.
Tan delta, also called loss angle or dissipation factor testing, is a diagnostic method of dielectrics to determine the quality of the insulation.

The evaluation of the cable's resistance to the action of external factors acting on partial capacitances and the tangent of the dielectric loss angle of the insulation gaps between the wires.
The tangent of dielectric loss angle can be evaluated using the relation given as,
