AUTOMATIC CAPACITANCE AND TAN DELTA TEST SET

We can also say that the healthiness of an electrical insulator can be determined by the ratio of the resistive component to the capacitive component. For good insulator, this ratio would be quite low. This ratio is commonly known as tanδ or tan delta. It is also referred to as dissipation factor (DF).Tan Delta, also called Loss Angle or Dissipation Factor, is a diagnostic method of testing cables to determine the quality of the cable insulation. This is done to try to predict the remaining life expectancy and in order to prioritize scheduled maintenance, replacement, or rejuvenation of the cable system under test.
