Annex A (normative) Exhaustive cleaning procedure for the test
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
Gives a method for the simultaneous measurement of conductance G and capacitance C helping the calculation of the dielectric dissipation factor tan delta of insulating liquids. The method proposed, is applicable both to unused insulating liquids and insulating liquids in service in transformers and in other electrical equipment.
