    Discussion of Auxiliary Power Source Open-Phase Protection in Nuclear Power Plant by Shunhua WU, Houjun QIAN, Tianwei WANG, Yupeng SUN, Jiangang CHEN, Chuanyang CAO, Jianfeng DONG, Zhenhua ZHAO

    Published 2025-07-01
    “…Besides the near-end open-phase, the open-phase protection should consider the far-end open-phase and neutral ungrounded. [Method] Based on the analysis of voltage and current behavior of the auxiliary transformer in nuclear power plant during the near-end open-phase and far-end open-phase failure, the different points of voltage, current, and zero-sequence impedance in normal operation and fault operation were identified to set open-phase protection. …”
