Description

IEC 61620 Ed. 1.0 b – Insulating liquids – Determination of the dielectric dissipation factor by measurement of the conductance and capacitance – Test method

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.
