Abstract
The article presents problems occurring during remote temperature measurement of lashing clamps of bridge connections on high voltage poles using thermal imaging cameras. The basic metrological parameters of thermal imaging cameras are described. On this basis, typical errors made during the inspection of high voltage lines supplying power substations are presented using infrared cameras. Researching the possible solutions for the problems of remote temperature measurement of small objects of electricity power systems—on the example of lashing clamps of bridge connections on high voltage poles in the proposed paper and showing the basic metrological aspects and parameters of thermal imaging cameras are important because, in this way, it is observed to eliminate costly interruptions in the supply of electricity associated with the breaking of power lines. Small objects are quite difficult to be controlled and monitored on large grids and on large powerline poles; thus, it is very challenging to interpret the data offered by thermograms. The problem of remote temperature measurement of small objects in electrical power engineering is very important from the point of view of the quality and reliability of electricity supply. Obtaining early warning information about the occurrence of overheating, e.g., on lashing clamps of bridge connections, is very important, as it eliminates costly interruptions in the supply of electricity associated with the breaking of power lines supplying high voltage switchgears or substations.
Highlights
In order to correctly measure the temperature of such an object, it is necessary to possess adequate knowledge and experience regarding the metrological capabilities of a thermal imaging camera when remotely measuring the temperature of a small object
It should be stated that the problem of measuring the temperature of extraction handles of bridge connections on high voltage poles is very important from the point of view of the reliability of electricity supply
Obtaining early information about the occurrence of overheating on such a connection is very important, as it eliminates costly interruptions in the supply of electricity associated with the rupture of power lines supplying high voltage switching stations or substations

Obtaining early warning information about the occurrence of overheating, e.g., on lashing clamps of bridge connections, is very important, as it eliminates costly interruptions in the supply of electricity associated with the breaking of power lines supplying high voltage switchgears or substations. This article describes the basic metrological parameters of a thermal imaging camera, important in the interpretation of the remote temperature measurement of small objects. Based on this knowledge, a practical example is provided as to how to correctly remotely measure the temperature of a lashing clamp of bridge connections of a power line. For this purpose, at the beginning of the article, the basic metrolo observational and measurement thermal cameras are described
