In general for electrical component, Ten delta means that the tangent value of insulating material. what is tangent value of IM? it is nothing but the dissipation factor. what is dissipation factor? The ratio of Power/ Voltage-Ampear (W/VA). so finally in simple words Tan delta testing is nothing but to find out the health of insulation OR insulating material.The test can be performed on Cables, power TR's or any electrical component.
hope i am able to answer
