GB/T 1094.23-2019
ActivePower transformers—Part 23: DC magnetic bias suppression devices
电力变压器 第23部分:直流偏磁抑制装置
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for DC magnetic bias suppression devices used in power transformers. It is applied in high-voltage AC power systems where geomagnetically induced currents or HVDC ground electrode currents cause DC bias, particularly in ultra-high voltage (UHV) and large-capacity transformers. The standard ensures these devices effectively mitigate core saturation, harmonics, and vibration risks to maintain transformer reliability and grid stability.
