    Abstract - (Show below) - (Hide below)

    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.
