- Scope
- This standard proposes methods for measuring the dielectric loss factor tanδ and capacitance of high-voltage power equipment, test wiring and judgment standards, focusing on various influencing factors of on-site measurements, possible errors and technical measures to reduce errors. This standard is suitable for measuring the dielectric loss factor tanδ and capacitance of high-voltage power equipment insulation under conditions such as power plants, substations, repair workshops, and laboratories.
