The development of the relay protection based on open architecture is a relevant direction of electrical and electronic engineering. The paper presents the problem of the modern microprocessor-based relay protection that consists in the impossibility of the element replacement with alternatives from other manufacturers. The literature review on the reed switches application for relay protection, traditional and open-source solutions are given. Τhe structural scheme of the processes and relay protection device with different modules and the use of open-source communication and Industrial Internet of Things is demonstrated. The goal of the further research of sensibility, selectivity and reliability is set.
