Документ Quality control and evaluation of the life cycle insulated power cables XLPE(Global Science Center LP, Budapest, 2021) Gontar, Yu. H.; Kiessaiev, O. H.; Antonets, T. Yu.The undoubted advantages of cables with XLPE insulation in comparison with cables with impregnated paper insulation are considered. Such cables are more reliable in operation. The need for design is based on technological and design features, on the number of defects, on the technology to be prepared and by the minds of the operation. Reliability is determined by technological and design features, the absence of defects, manufacturing technology and operating conditions. Tests are an integral part of cable life cycle. Life cycle assessment is an important tool for determining the actual service life. Analysis of the data obtained during the tests allows you to assess the life cycle of the cable.Документ Guidelines of calculation and graphical performing the task on the topic "Calculation of linear DC electric circuits"(Видавничий центр НТУ "ХПІ", 2020) Rezynkina, M. M.; Kiessaiev, O. H.; Rezynkin, O. L.; Lytvynenko, S. A.These guidelines contain the necessary theoretical basis, tasks and examples of calculations of linear DC electric circuits. The task is on the topic "Linear DC electric circuits" of the first semester of students' study of the courses: "Theoretical Basics of Electrical Engineering", "Theory of Electrical and Magnetic Circuits", "Theory of Electric Circuits". The first semester of students’ study in these courses is significant for further study of both theoretical basics of electrical engineering and other specialized disciplines of electrical engineering, for which theoretical basics of electrical engineering are the basic discipline. During the first semester, students learn the basic laws and methods of calculation of DC and AC circuits (Ohm's and Kirchhoff's laws, mesh current method and nodal potentials methods, the equivalent generator method and the superposition method), which are the base for practical calculations of electric circuits for various purposes. Self-study students’ work by this task should be considered as the basis for successful learning in the next semesters. At this task performance, students can use sources at the end of the guidelines, which contain the theory and examples of the considered problems solution. Guidelines are for students of specialties 141, 151, 171 of full-time and distance forms of study.Документ Guidelines of calculation and graphical performing the task on the topic "Linear electric circuits of harmonic current"(2020) Rezynkina, M. M.; Kiessaiev, O. H.; Rezynkin, O. L.; Lytvynenko, S. A.The methodical instructions are intended for students of the specialties 141 "Electric Power, Electrical Engineering and Electromechanics", 151 "Automation and computer-integrated technologies", 171 "Electronics" of full-time and distance forms of study.
