Work- Aim - increasing of the operation effectiveness of electric systems nodes with motors due to improving the principles of fulfilment of the protection and diagnostics. As result of the work fulfilment were accorded the development the principles of construction of centralized system nodes automation, which carry out the protection from between-phases short circuits, carry out the automatic diagnostics of electric motors connections, and also ground fault protection. The theory bases of centralized automation systems construction are offered. The mathematical model of electric system node with motors taking account the isolation was worked up. The researches of normal and abnormal duties were executed with help of the model. The protectively-diagnosing automation, which provide the protection from ground fault and isolation control of connection were worked up and inculcated. The method of determination of complex phases isolation conductivities to relation to earth and the recommendation of increasing of operation effectiveness of ground fault protection was worked up.
