Scope

Main technical content: This standard specifies the model, usage conditions, technical requirements, testing methods, test items and rules, marking, packaging, transportation, and storage of the arc-extinguishing device for grounding the faulted phase through reactors (referred to as the device). This standard applies to neutral-point non-effective grounding systems with a nominal voltage of 6kV to 35kV. When a single-phase grounding occurs, the device actively grounds the faulted phase to extinguish the arc and provide protection. For devices used in neutral-point non-effective grounding systems with a nominal voltage below 6kV, this standard can be referenced for implementation.
