What is tan-delta test ?

Tan-delta test is also know as dielectric losss testing. Dielectric loss refers to the energy loss that occurs in a dielectric material (such as the insulation of a transformer) when an electric field is applied to it. The dielectric loss is caused by the electrical resistance of the material, which results in the conversion of electrical energy into heat.
