DF test sets try to measure a single capacitor, but if the test object has additional phantom circuits, the results look strange. For example, with bushings, three-winding transformers and the inter-phase insulation of rotating machinery, measured DF values are sometimes negative. Since DF is a measure of watts loss, negative DF corresponds to watts generation. As insulation cannot generate

Dissipation Factor (quantitatively similar to Tanδ or power factor) testing has long been used as a means to measure the quality of the electrical insulation in stator coils and bars rated 3.3 kV and above. A variation of the dissipation factor (DF) test is called the DF “tip-up” test (also called the power factor tip-up or Δtanδ test). The tip-up test is a measure of void content
