function and design of a microcontroller-based protection unit for substation and switchgear of terminal user is described in this paper. The Unit is self-powered and is suitable for the detection and protection in both neutral isolated system and neutral grounded system. It provides a novel and practical solution for terminal user of switchgear.(3.
