HJ 681-2013 Electromagnetic Environment Monitoring Method for AC Power Transmission and Transformation Projects (Trial Implementation) (English Version)
This standard specifies the monitoring method for the upper-frequency electric field and upper-frequency magnetic field generated in the upper reaches of AC power transmission and transformation. This standard is applicable to AC power transmission and transformation projects with voltage levels of l10kV and above. Electromagnetic environment monitoring for AC power transmission and transformation projects with voltage levels of 10kV and above can be implemented with reference to this standard.a
