Application of thermovision in maintaining high voltage transmission network

The paper presents the efficiency of the application of thermovision testing in the process of detecting potential spots of protection in the regular and preventive maintenance of power plants. The above examples of tests were made in 2016 and 2017 in substations under the jurisdiction of Elektroprenos BiH, which are covered by the Visegrad field unit during the maintenance process. Termovision testing is an integral part of regular testing throughout the year to identify potential breakdown sites that will be repaired and repaired on time. Using this approach, the efficiency and availability of the supervised system has been increased, with potential failures observed during maintenance not occurring in the upcoming period, which shows that this method is very effective in the case of early removing potential “critical” points in the plant. Infrared cameras were used to control, control, and diagnose the condition of the elements in the power plants: FLIR ThermaCAM PM 675 and the Fluke Ti400 9Hz Thermal Imager model. Test results are presented in this paper.
