  "textContent": "This application presents an adaptive arc suppression method for ground faults in distribution networks, merging active and passive relay protection strategies. The method proceeds as follows: based on collected ground parameters, the fault phase is identified; compensation current is calculated from the fault's electromotive force, ground leakage resistance, and ground capacitance; current is injected at the neutral point according to the compensation current; finally, the arc suppression scheme is executed based on the zero-sequence voltage of the network's busbars. This approach incorporates both voltage- and current-based methods, addressing the limitation of fixed operation scenarios in traditional arc suppression methods. By quickly adapting to various fault situations, this method ensures an efficient and prompt response tailored to specific scenario requirements.",
