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
Annex ZA Normative references to international publications with
their corresponding European publications

Covers a procedure for the simultaneous measurement of conductance G and capacitance C, which enables the calculating of the dielectric dissipation factor tan of insulating liquids. Applicable both to unused and inservice insulating liquids, in transformers and other electrical equipment.
