The article deals with the main methodological aspects of the metrological provision of information and measurement systems in transport infrastructure projects. The object of study is the means of information-measuring systems of electric power objects of transport of Ukraine. The purpose of the work is to study the metrological provision of information and measurement systems at electric power facilities, in particular transport, which allow to solve many problems related to registration of operating modes of power systems, determination of electrical and time parameters, finding damage on power lines, diagnostics of electrical equipment and others. The research method is a systematic analysis of the metrological assurance of reliable, economical and high-quality operation of electric power objects due to the introduction of synchronized measurements on large electric power objects at large electric power objects. The regulatory framework for metrological support is the State Standards and other documents of the State System for Ensuring Unity of Measurements, the relevant normative documents of the State Standard of Ukraine, methodical instructions and recommendations. The technical basis is the system of state standards and standard measuring instruments, which ensures their reproduction with the highest accuracy; a system of working standards and exemplary measuring instruments by means of which the sizes of units of physical quantities are transferred to the working measuring instruments. As well as a system of standard samples of the composition and properties of substances and materials, which ensures the reproduction of units, composition and properties of substances and materials. The purpose of metrological support is to improve quality, increase production efficiency, use of material values and energy resources, as well as scientific research. The most effective way to improve the reliability, economy and safety of power equipment is to use methods and techniques for technical diagnostics. Due to the use of monitoring systems for monitoring and diagnostics of the electrical parameters of the electric power objects of the railways, both the renewal time of the power supply (associated with the restoration of train traffic) and the corresponding economic losses caused by emergency shutdown are minimized, as well as the costs associated with the operational repair works to eliminate the effects of damage. The characteristics of digital registrars and monitoring systems offered by the leading manufacturers in the electricity market are regulated by international standards. The made comparisons of the accuracy of measurements of different devices for recording the parameters of the modes show similar indicators and confirm the possibility of using the system of monitoring the mode parameters in the problems of estimating the state of power systems. The results of the study can be used in technological processes in transport infrastructure projects when using digital devices as a measurement tool for parameter control and monitoring of electric networks both in Ukraine and abroad.
