GB/T 33977-2017 Active
GB/T 33977-2017 Methods to quantify the steady state,power-frequency electromagnetic fields generated by HV switchgear assemblies and HV/LV prefabricated substations
Abstract
This standard provides practical guidelines for the evaluation and documentation of external electromagnetic fields generated by high-voltage switchgear and high/low-voltage prefabricated substations. A summary of the basic requirements for measuring and calculating electric and magnetic fields is included in GB/T 3906 and IEC 62271-201 for switchgear, and in GB/T 17467 for high/low-voltage prefabricated substations.
