ActiveSpecification for single-phase-to-ground fault feeder selection device based on traveling waves for neutral non-effectively grounded system
中性点非有效接地系统单相接地故障行波选线装置技术要求
Application Summary AI generated
This standard specifies technical requirements for devices that detect single-phase-to-ground faults in power distribution systems with neutral points that are not directly grounded (such as arc suppression coil or ungrounded systems). It applies to traveling wave-based feeder selection equipment used in 6-35 kV distribution networks to accurately identify the faulted line during a ground fault. The standard ensures reliable performance in substations and industrial power systems where quick fault isolation is critical for safety and continuity of supply.
