Scope

This International Standard describes a method for the simultaneous measurement of conductance (G) and capacitance (C) enabling the calculation of the dielectric dissipation factor (tan delta) of insulating liquids. The proposed method applies both to unused insulating liquids and insulating liquids in service in transformers and in other electrical equipment. The standard is no substitute for IEC 60247; rather it complements it insofar as it is particularly suited to highly insulating liquids and it recommends a method of measurement for these liquids. This method allows values of the dielectric dissipation faxtor as low as 0,0000001(10-6) at power frequen
