Double entry it is method of registration of economic operations accounting, applied to detect errors. The application of the method in differential protection leads to increased reliability of technical solutions. By providing redundant processing of information about currents measured at the ends of the protected object, and is formed in a special matrix that implements the reliable operation of the differential protection, eliminating its excessive action when damaged the current transformers or communication lines. To assess the reliability of protection used the method of Markov chains. The obtained results allow to make a conclusion about the prospects of implementing a differential protection using the method of double entry in the electrical networks.
