IEC TS 60076-23:20 18（E）规定了抑制电力变压器和换流变压器DC磁偏置的设备要求。它包括对使用条件、结构、测试、包装、运输和储存的要求。 这些装置连接到电力变压器和换流变压器的中性点，以在HVDC系统以单极接地返回模式或双极不平衡模式运行的情况下抑制DC偏置电流。在专用金属回流HVDC系统的情况下，所述装置可用于在诸如DC线路故障的瞬态条件期间减轻流经电力变压器和换流变压器的DC杂散电流。 本文件适用于在电压高于110kV的电力系统上以50Hz和60Hz的频率工作的DC磁偏置抑制装置。

IEC TS 60076-23:2018(E) specifies requirements for devices for the suppression of DC magnetic bias of power transformers and convertor transformers. It includes requirements for service conditions, structures, testing, packing, transport and storage.
The devices are connected to neutral points of power transformers and converter transformers to suppress DC bias current in the case an HVDC system is operated in monopole ground return mode or bipolar unbalanced mode. In the case of dedicated metallic return HVDC system, the devices are useful to mitigate DC stray current flowing through power transformers and converter transformers during transient conditions such as DC line fault.
This document applies to DC magnetic bias suppression devices for operation at frequencies of 50 Hz and 60 Hz on power systems having voltages above 110 kV.
