Surge Arrester Simulation in Fourier Transients Programs of Transmission Systems
نویسنده
چکیده
The importance of simulating surge arresters in fast transients programs stems from their useful property as a means of controlling switching overvoltages in EHV and UHV systems. The paper proposes a surge arrester model to be used in conjunction with a transient program based on Fourier transform technique. The validity of the proposed model is demonstrated by computational results.

Simulation of metal oxide surge arrester dynamic behavior under fast transients
Data on characteristics of metal-oxide surge arresters indicates that for fast front surges, those with rise times less than 8μs, the peak of the voltage wave occurs before the peak of the current wave and the residual voltage across the arrester increases as the time to crest of the arrester discharge current decreases. Several models have been proposed to simulate this frequency-dependent cha...
متن کاملPerformance of Surge Arrester to Multiple Lightning Strokes on Nearby Distribution Transformer
Overhead distribution lines are prone to lightning overvoltages due to their configurations and characteristics. Metal Oxide Varistor (MOVs) arresters for many years have proven to be more advantageous than others arresters in lightning surge protection; therefore it is worthwhile to continually assess the behavior and performance of these arresters to different kind of overvoltages caused by l...
