What is tan delta test : Sometimes it is also referred to as dissipation factor. Principle principl e of tan delta test test a pure insulator when is connected across line and earth, it behaves as a capacitor.

This is done to try to predict the remaining life expectancy and in order to prioritize cable replacement and/or injection.

11+ Tan Delta Test Circuit Diagram. Loss tangent delta test general: Tan delta measurement tan delta measurement is a simple and effective method to confirm the dielectric condition of medium voltage cables. The results reveal how contaminated, damaged, or water tree strewn the insulation has become. The open circuit test and short circuit test is carried out to determine the various losses, efficiency and also impedance, resistance and leakage reactance of the transformer.
