Abstract
This paper investigates key technologies for reliable electrical monitoring in complex power environments. Core techniques include anti-electromagnetic interference sensing, multi-source signal isolation and filtering, characteristic signal injection with non-contact identification, multi-channel real-time data acquisition, and rapid fault recognition with protection interruption. Experimental analysis demonstrates stable monitoring performance and effective fault detection under electromagnetic disturbance conditions.
