Testing of Selected Surge Protection Devices in the Context of the Possibility of Ensuring the Reliability of Power Grids

The paper aims to analyze the parameters of prototypes new overvoltage protection devices for power grids—a multi-chamber insulator arrester (MCA) and a long flashover (LFA). article presents research results on determining actual MCA LFA impact characteristics. Moreover, were compared assess effectiveness devices. presented in this will supplement missing information about They make it possible evaluate possibility using type spark gap based multi-segment system high-voltage networks specific country. analysis its properties against background atmospheric overvoltages their high voltage lines be carried out by assessing tested device laboratory conditions. tests also applying standardized lightning switching surges map processes grid elements. Two different generators used purpose. proposed allow learning influence structural elements operation
