The DDF is a measure of power loss when an external field is applied to an insulating medium. It gives tangent of the dielectric loss angle which is also known as loss factor or tan‐ δ . The insulation (of any HV equipment) can be represented as a series or parallel combination of a capacitance and a resistance.
