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.
