| Abstract | The article tells about various malfunctions and sudden refusals arising in use of electrodriving fittings as a part of power units of NPP, it can lead to safety decrease and big economic losses. For definition of fittings technical condition on the nuclear power plant the analysis of spectrum and analysis of bending around the signal of the current consumed by the equipment in the course of work is applied. For the purpose of sensitivity increase of diagnosing the phase and plane method based on the analysis of a phase portrait of a signal of current is offered. It is shown that the best quality of diagnosing is reached when using the regular methods connected with the analysis of bending around and spectrum of current signals together with an assessment of phase portraits. |
