Mobile Measuring Complex for Conducting an Electric Network Survey

Abstract

An energy audit of the electrical network is required in the process of constructing new electrical networks as well as in justifying the reconstruction need of existing ones. In this chapter, the structure of a mobile measuring complex has been developed to conduct an electrical network survey without disconnecting consumers. The complex can be used to inspect 0.4 kV electrical networks and microgrids of the same voltage class and allows data collection on voltage losses and electric power losses in network elements such as a power lines (electric transmission line), and power transformers. The energy audit is conducted without disconnecting consumers in order to avoid an undersupply of electricity as well as to determine the real operating modes of power networks. Ultimately, the use of the developed measuring complex will increase the reliability of the power supply to consumers and ensure the required quality of the electricity supplied to them.

Identification power line sections with increased electricity losses using sensors with Wi-Fi technology for data transmission

“…Figure 1 shows the appearance of PTEM -3. To identify power line sections with increased losses, it is necessary to install the simultaneous installation of several PTEM-3 devices at different sections of the power transmission line, to ensure their autonomous operation and then processing the received data [5]. Since the devices are synchronized in time, it is possible to carry out a comparison of these data and identify the sections where the energy losses are too high.…”

Universal Switch for Measuring the Resistance of the Grounding Device Supports of the 110 kV Overhead Power Line

“…Studying the writings (Gracheva and Naumov, 2019;Koliushko and Rudenko, 2019;Kosyakov et al, 2019;Vinogradov et al, 2020), we discovered that there is no mathematical model to describe the process of measuring the resistance of the protective device of the 110 kV OHL supports. This is a gap in the research that aims to increase the efficiency of resistance measuring of those protective devices.…”

The method of extending drone piloting autonomy when monitoring the technical condition of 6-10 kV overhead power lines

“…For this reason, it is impossible to equip all power lines of this voltage with stationary monitoring systems. Therefore, it is necessary to create mobile measuring complex (MMC) [10], which make it possible to conduct a survey of a large number of power lines in a rather short period of time. For today the existing mobile electrical laboratories are mainly intended for testing and diagnosing electrical equipment of substations, switchgears and cable lines, measuring insulation resistance of power and current transformers, highvoltage switches and relay protection.…”
