Abstract

The work shows the high efficiency of diagnosing electrical equipment using the modulated stator current of electrical machines associated with rotor defects, with the presence of interturn and interphase closures, the vibriation-diagnostic parameters of their bearings, as well as the harmonic components of combinational frequencies and pulsations, appearing but for the non-linear volt-amperic characteristics of traction transformer and for the converters of electric locomotives. The scheme of integral informational environment of continuous diagnostics of electric devices of railway energetics was given.
