Scope: This standard specifies the measurement methods for dielectric loss factor, relative permittivity and DC resistivity of liquid insulating materials at the test temperature. This standard is mainly for reference tests on unused liquids, but it is also applicable to transformers in operation. , cables and other liquids in electrical equipment. However, this standard is only applicable to single-phase liquids. When making routine measurements, the simplified method and the method described in Appendix C can be used. For non-hydrocarbon insulating liquids, other cleaning methods are required.
