The SHK‑XHG series provides arc‑quenching, harmonic elimination, line selection and over‑voltage protection for 3 ~ 35 kV three‑phase ungrounded power systems. It uses patented technologies to quickly detect and isolate single‑phase ground faults, limit over‑voltages, and record fault events.
The manual describes the device’s main components, optional functions, technical parameters, mechanical dimensions, environmental limits, ordering information, and procedures for installation, commissioning, and maintenance. This manual is written in Chinese.
