Line surge arresters (LSA) are designed to prevent ground faults and short circuits in power lines caused by lightning or switching overvoltages. Insulator flashovers, voltage dips and interruptions are prevented by eliminating all lightning and switching overvoltages above the insulator insulation level (the lightning-impulse withstand level, or LIWL for short).
Installation of line surge arresters at recommended locations along the line in accordance with our line simulation ensures anhanced overvoltage protection. Selecting the optimum line surge arresters, especially in terms of their quantity and installation locations, significantly improves the reliability of the overall line system and the quality of power that it supplies. We offer line surge arresters for system voltages up to 800 kV and an energy discharge capability of 3.6 C.
