Understanding Tan Delta and Dielectric Loss
Knowing Tangent {Delta | Δ | D) and Insulating Dissipation are vital parameters of determining the health of electrical insulation systems . Tan Delta, also referred as loss tangent, represents the relationship of reactive current to true current within the electrical medium. A higher Tan Delta value generally suggests a less desirable insulation quality due to factors such as impurities, water, or deterioration. Dielectric Loss, directly related to Tan Delta, quantifies the amount of energy consumed as thermal energy within the material, and its extent is linearly affected by Tan Delta and the dielectric permittivity .
