Influence of Spark Gap Parameters on the Strength of the Surge Protection Device and the Method of Its Selection

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