For full use of information in multiparameter relay protection it is advisable to use statistical detection theory and a Bayesian criterion of minimal average decision risk. A method for combining the signals from a set of separate relay protection starters is proposed in order to improve its sensitivity. It is shown that combining the measurements of the univariate relay protection measurement devices yields the same result as combining the binary signals of starters using these measurement devices.
