Insulating liquids. Measurement of relative permittivity, dielectric dissipation factor (tan δ) and d.c. resistivity Ingestion-build-109673 pid=0000000000199758411 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
