Tan delta is the tangent of the loss angle of an insulation system, the angle by which the current through the insulation under alternating voltage departs from a purely capacitive current. It is the dissipation factor expressed as a ratio, and it rises as the insulation takes up moisture, ages or develops conductive paths.
