In order to acquire the real-time lightning electromagnetic radiation field in large extent, a new automatic acquisition system is developed based on virtual instrument. Besides the essential function components such as PXI-6608 Counter/Timer and PXI-5105 Data Acquisition Card, the lightning detection stations and GPS receiver are introduced to accomplish the signal synchronization and continuous...
A time domain electromagnetic field approach is proposed to investigate the lightning surge impedance of the full scale UHV tower with grounding system. The model, which is validated by comparing the result to those of other method, can be used to analyze the lightning surge performance of a power line more accurately. Finally, this method is applied to analyze the surge impedance and potential of...
