Abstract: The paper aims to analyze the factors affecting the parameters of surge protection devices with a spark gap and assess the impact of changing these parameters on the level of overhead line strength. For this purpose, this paper contains the results of tests that show the assessment of the impact of changing the spark gap parameters on the voltage–time characteristics of selected protection devices in the range of negative and positive polarity. The paper presents how the change in the parameters of the component element of the surge protection device, which is the spark gap, may affect the selection of the line surge protection method. In addition, the paper presents a method of assessing the strength of an overhead line, taking into account the case of installing surge protection devices at the insulators. The implementation of these tests supports further activities aimed at the actual values of parameters affecting the strength of overhead lines.
