The methods of determining the probabilities of "mean-cycle-to-failure", "mean-cycles-between-failures" are devised; the algorithm of the control system rational element base suggested and service conditions. Time relays, intermediate relay with an application of modern hercons and semiconductors are created on the basis of the theoretical research carried out. The test specimens manufactured are set up on the electric locomotives ЧС2-063, ЧС2-093 in Dnepropetrovsk deport and are being tested in service Product Description popup.authors popup.nrat_date 2020-04-03 Close
