The paper offers an integrated approach to developing a system of guaranteed uninterrupted power supply for industrial equipment and systems ensuring plant’s operation safety.

Malinovsky D.I. Power sources: reliable energy for industrial automation

Reliable power sources are paramount for industrial automation, because industrial production, as against, e.g., military machines or home appliances, is never stopped and is critical for ensuring welfare and existence of contemporary human society.

Pavlov V. OVEN power units and their application

At first sight, power units are rather simple manufacture. But at more attentive examination, we make sure that they are sophisticated electronic devices. The paper presents OVEN power units and explains the reasons of their durability.

Ivanov K.B. A review of Mean Well’s novelties

Key performance data and application areas of novel power sources from Mean Well (Taiwan) are presented.

Power electronics from Omron

Basic capabilities and design features of Omron’s new K8 Series relays and S8TS modular power sources are outlined.

Yachkula N.I. DUGA MT digital protection device against arc shorts

Internal faults through a voltaic arc are extremely dangerous for 6…10 kV switch-yards. Such accidents can entail on-the-job injuries and material losses up to the full destruction of the package substation as well as indirect losses related with long-term power supply interruption for users. The topicality of the problem stipulated the introduction of the requirement about switch-yards protection devices into RAO UES of Russia guidelines. The devices should protect package substations against voltaic arcs and ensure fast response, absolute selectivity, and high sensitivity. To overcome the challenge, Mechanotronica Scientific and Technical Center has developed DUGA MT digital protection device against arc shorts.

Plotkin I.R., Tverdov I.V.

Alexander Electric Power Sources (AEPS) specializes in development and manufacture of power supply modules for industrial automation, aerospace industry, telecommunications and related systems both ground-based and on-board. in For a long time, AEPS has been supplying Russian market with AC/DC and DC/DC modules in the 5…1200 W power range. The reliability of power modules depends not only on circuitry and electronic components, but rather on external noise immunity. At the same time, the modules themselves are high-frequency pulse converters of electric power and thus are radio noise sources for electronic equipment. In order to help the clients facing these problems, AEPS manufactures protection tools such as RFI filtration and overvoltage protection modules and UPS.

Babich V.I.Some electrical equipment inspection tasks and the hardware to accomplish them

Electrical equipment inspection tasks often require the estimation of its reliability and operation efficiency. As far as process variables deviation from design values are fraught with high unplanned maintenance costs, the reliability of equipment should be also considered as a business factor and evaluated subject to economic criteria. In this context, equipment inspection is considered as a method for improving the profitability of electrical equipment operation.

Shpiganovich A.N., Yermolov S.A The analysis of power supply systems operation at industrial enterprises

Simulation techniques is applied for analyzing the emergency development caused by three-phase fault of substation’s voltage distribution buses. Based on the results obtained, it is possible to identify the segments of industrial power networks the most prone to failures and to create the optimal operation algorithm for relay protection and automation devices.
