The features of configuring software and hardware of modern data acquisition systems as part of a digital substation to comply with the international standard IEC 61850 are considered. Given recommendations for energy efficient software and hardware configuration for 110 kV, 6-35 kV and 0.4 kV power consumption level which allow you to increase the reliability of the system by 1.5-2 times.

Described the research results of hardening coatings coating modes influence on the microstructure of the surface layer of machine parts. Electroacoustic coating was used as a coating method. X-ray structural analysis and electron microscopy were used to investigate the microstructure of the coatings. The results obtained can be used to determine the optimal technological modes of coating.
