On the question of the taxonomical status of tribe Procleticini Pennington (Heteroptera: Pentatomidae)

Probable taxonomical connections of tribe Procleticini with others taxa of shielded-bugs are a subject of this paper. The parameres and aedeagi of Antestiella bequaerti, Antestiopsis cruciata, Arocera acroleuca, A. apta, Bolbocoris variolosus, B. inaegunalis, Dendrocoris contaminatus, Holcogaster exilis, H. longicornis and Thyanta custator are described in this paper. Aedeagi are described in completely straightened and inflated condition. The general features of a structure of genitals for the specified species are considered in paper. These features are characteristics of a structure of parameres, theca, phallobase, ventro-lateral and dorsal lobes of conjunctiva. Dorsal lobes of conjunctiva have not been discovered at representatives of Asopinae, Discocephalinae, Phyllocephalinae and Podopinae with Pentatominae, except for the representatives of tribes, which are considered in this paper. Probably, it is uniform for these tribes and features, or at least, for Procleticini and Antestiini. Possible taxonomical value of these features at definition of a place Procleticini in system of Pentatomidae is discussed

The brown marmorated stink bug Halyomorpha halys (Stål, 1855) (Heteroptera: Pentatomidae): expansion of its range in the European part of Russia, description of the imago and larvae, and the diagnostics of the species

A new regional record of Halyomorpha halys (Stål, 1855) from the territory of the European part of Russia is given; this find indicates the further spread to the north of this invasive species, first recorded in Russia on the Black Sea coast of the Caucasus three years ago. Until now, the northernmost place of finding of H. halys in Russia was Staromyshastovskaya Village of the Dinsky District in the Krasnodar Region. In 2019, stable populations of the species were found in Rostov-on-Don (Rostov Region). The article also provides an illustrated complete morphological description of the imago and all larval instars, as well as data for identification of the species, including characters that distinguish H. halys from all the more or less similar species of the shield bugs in the fauna of European Russia

Monitoring of electrical energy quality on the traction substation input

For the implementation of measures to maintain the quality of the energy industrial enterprises have to spend a significant material and monetary assets. In this regard, significant is the feasibility study of the allocation of such funds and, primarily, the determination of the economic damage arising from low quality of electricity. The reliability of the electricity metering system, relay protection and automation of modern digital substations depends on the quality of electrical energy. At the present time to improve the reliability of the substation operation it is necessary tomonitor indicators of quality of electric energy, allowing you to take organizational and technical solutions for their improvement. Monitoring the power quality at the input traction substation has shown that indicators such as the coefficient of the n-th harmonic component of the voltage does not meet the standards GOST 13109-97. The source of higher harmonics is a voltage Converter used on the locomotive. To eliminate higher harmonics in the supply network for traction substations will need to install power filters. Today, the USB-analyzer of power quality «Digital system for the measurement of electrical energy quality» type of DSMEEQ of accuracy class 0.2. Work energy requires reliable and quality electricity supply to consumers. The new model of balancing energy market are bilateral contracts. The main task of this market, it ensure the stable and reliable operation of the unified energy system of Ukraine, that is, transmission and supply of electricity of appropriate quality.Надежность работы системы учета электроэнергии, релейной защиты и автоматики на современных цифровых подстанциях зависит от качества электрической энергии. В настоящее время для повышения надежности работы подстанции необходимо контролировать показатели качества электрической энергии, что позволяет принимать организационные и технические решения по его повышению
