HIGH-FREQUENCY DIAGNOSTICS OF INSULATION IN WINDINGS OF MOTORS

The physical analysis of the processes, physical and mathematical modelling and mathematical analysis have been performed. The algorithms of the design at frequencies up to 1 MHz of the magnetic circuits and loop parameters, coil and pahse of the motor winding, loop supervoltages in the windings and also the optimization bases for test and check of the loop insulation and devices for detection of the loop short circuits in the windings of the induction motors have been developed.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
