Insulating liquids - Measurement of relative permittivity, dielectric dissipation factor (tan phi) and d.c. resistivity

DS/EN 60247-2004 发布历史

This International standard describes methods for the determination of the dielectric dissipation factor (tan ä), 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 phase liquid only. When it is desired to make routine determinations, simplified procedures, as described in Annex C, may be adopted. With insulating liquids other than hydrocarbons, alternative cleaning procedures may
