METROLOGICAL ANALYSIS OF AN INTELLIGENT REFLECTOMETER FOR MONITORING POWER LINES
(pp. 36-45)

Abstract. The article provides an analysis of the sources of errors of reflectometers. The main error of reflectometers is the methodological component, which is determined by the error of setting the phase velocity of the pulse. The phase velocity of the pulse depends on various external factors. The instrumental component of the error is due to the instability of the reflected pulse shape and the presence of noise in the signal. Based on metrological analysis, an intelligent reflectometer was developed for monitoring overhead power transmission lines. The developed reflectometer contains blocks and nodes to compensate and reduce the main components of the total error. The developed reflectometer makes it possible to increase the accuracy of determining the accident site and reduce the recovery time of the line, and, consequently, increase the reliability of power supply.

Keywords: emergency modes overhead power lines, monitoring overhead power lines, line with distributed parameters, tools for fault location of overhead power lines, reflectometer.
