ActiveInsulating liquids - Measurement of relative permittivity, dielectric dissipation factor（tanδ）and d.c. resistivity
液体绝缘材料 相对电容率、介质损耗因数和直流电阻率的测量
Application Summary AI generated
This standard specifies test methods for measuring the relative permittivity, dielectric dissipation factor (tanδ), and d.c. resistivity of liquid insulating materials. It is applied in the electrical power industry for quality control and acceptance testing of transformer oils, capacitor oils, and cable impregnants. The measurements help assess insulation condition and detect contamination or degradation in high-voltage equipment.
