ActiveInsulation co-ordination - Part 2: Application guide
绝缘配合 第2部分：使用导则
Application Summary AI generated
This standard provides guidance on applying insulation coordination principles to high-voltage power systems and equipment, covering the selection of insulation levels and the determination of overvoltage protection measures. It is specifically used by engineers in the design, testing, and operation of electrical installations such as transformers, switchgear, and transmission lines operating above 1 kV. The guide helps ensure reliable performance and safety by detailing how to assess voltage stresses, choose appropriate clearances, and coordinate surge arresters with equipment insulation.
