IEC/TR 62271-208:2009为高压开关设备组件和高压/低压预制变电站产生的外部电磁场的评估和记录提供了实用指南。概述了IEC 62271-200和IEC 62271-201所涵盖的开关设备组件以及IEC 62271-202所涵盖的预制变电站测量或计算电场和磁场的基本要求。本技术报告适用于额定电压52 kV及以下的设备- 频率从15赫兹到60赫兹。

IEC/TR 62271-208:2009 gives practical guidance for the evaluation and documentation of the external electromagnetic fields which are generated by HV switchgear assemblies and HV/LV prefabricated substations. Basic requirements to measure or calculate the electric and magnetic fields are summarised for switchgear assemblies covered by IEC 62271-200 and IEC 62271-201, and for prefabricated substations covered by IEC 62271-202. This technical report applies to equipment rated for voltages up to and including 52 kV and power-frequencies from 15 Hz to 60 Hz.
