The mass introduction of new digital relay protection (RP) devices and the communications systems between them potentially makes it possible to increase the sensitivity of relay protection due to the introduction of multidimensional measurements. Amethod is proposed for effective combination of the measurements of a set of individual fault detectors, increasing the recognizability of RP modes. The method is based on the statistical theory of detection, the Bayesian criterion of minimizing the mean risk of decision-making.
