equal to each other within about one part in one thousand. In general, since the dissipation factor or power factor of insulating oils in good condition have decimal values below 0.005, the two measurements (terms) may be considered interchangeable.
The exact relationship between dissipation factor (D) and power factor (PF) is given by the following equations:
The reported value of D or PF may be expressed as a decimal value or as a percentage. For example:
Relative Permittivity (Dielectric
