Insulating liquids. Measurement of relative permittivity, dielectric dissipation factor (tan δ) and d.c. resistivity Ingestion-build-109673 interpret and use control charts:1 Scope This International standard describes methods for the determination of the dielectric dissipation factor (tan ), relative permittivity and d. c. resistivity of any insulating liquid material at the test temperature. The methods are primarily intended for making reference tests on unused liquids. They can also be applied to liquids in service in transformers, cables and other electrical apparatus. However the method is applicable to a single
