ASTM D924 Method for Dissipation Factor(Power factor) and Relative Permittivity(
4. Significance and Use4.1 Dissipation Factor(or Power Factor) - This is a measure of the dielectric losses in an electrical insulating liquid when used in an alternating electric field and of the energy dissipated as heat. A low dissipation factor or power factor indicates low ac dielectric losses. ...
