Insulating liquids. Measurement of relative permittivity, dielectric dissipation factor (tan δ) and d.c. resistivity Ingestion-build-111333 Annex B (normative) Training ofWhat is BS EN 60247 Insulating liquids about? BS EN 60247 describes methods for the determination of the dielectric dissipation factor (tan ), relative permittivity and d. c. the resistivity of any insulating liquid material at the test temperature. BS EN 60247 outlines methods that are primarily intended for referring tests on unused liquids. They can also be applied to liquids in service in transformers, cables, and other electrical apparatus.
