Measuring methods of relative capacitance, dielectric loss factor and DC resistivity are specified in the GB/T 5654-2007 standard for liquid insulating materials. Measurement principles, required instruments and operating procedures are described in detail, which are suitable for all kinds of liquid insulating materials. By following this standard, these key parameters can be accurately determined, providing a strong basis for mass control, performance evaluation and rational selection of liquid insulating materials in electrical equipment, and ensuring the safe and stable operation of electrical systems.
