WebDissipation 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). WebDefinition. One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of …
