cells
Annex B (normative) Simplified cleaning procedure for test cells
devoted to only one type of liquid
Annex C (informative) General considerations on the factors
influencing the conduction of liquids
Annex D (informative) Bibliography
Describes a method for simultaneous measurement of conductance G and capacitance C enabling the calculation of the dielectric dissipation factor tan delta of insulating liquides. Method applies to both unused insulating liquids and insulating liquids in service in transformers and in other electrical equipment.
