Résumé

Overvoltage protection devices are the most important apparatuses in the power networks which decrease the cost of power network designing. High voltage protection devices such as spark gaps, surge arrestors, and pin & cap insulators are needed in a power system to protect the system from overvoltage by deflecting the cross-currents. In designing a power system, it is necessary to consider the strength of protection devices under different ambient conditions. Protection devices should be tested under different voltages to ensure the reliability of the power system. In this paper, the experimental activities were performed on the investigation of the performance of the spark gaps, arresters and contaminated insulator strings under impulse lightning voltage in High Voltage Lab at Mississippi State University and results are obtained consistently. For this test, IEEE standards were considered to accord the ambient conditions at laboratory with standards.
