WG 23

IEC 62271-208: High-voltage switchgear and controlgear - Part 208: Methods to quantify the steady state, power-frequency electromagnetic fields generated by HV switchgear assemblies and HV/LV prefabricated substations


This TS follows the guidelines given with the safety and EMC guide to give common rules for the calculation and measurement methods of Electromagnetic Fields (EMF) in the field of High Voltage Switchgear and Controlgear. The TS is required to give guidance to the manufacturer and user of high voltage switchgear relating to EMF. A higher public sensibility concerning EMF and High Voltage Switchgear gives this TS a high market relevance.
The TS is not giving any definitions of EMF values. Only referring to TC 77.
