Model of over voltage control in transmission system

Abstract

This thesis offers the design of the impulse generator 1.2 / 50 μs, which applies for studying and generating the lightning impulse, to test the endurance of the electricity transmission line. Moreover, this study analyses the factors, which affects the impulse waveform by using Orcad program. The parts of prototype device can find in the general market. After the efficiency test of the electricity transmission line, the result shown that the device should have the high capability to endure the temporarily high impulse. This minimizes the dangerous from the electricity system.
