Lightning Transient Sensing, Monitoring and Application in Electric Power Systems

Lightning faults of the transmission lines are randomly distributed throughout the power system. In recent years, significant strides have been made in broadband-frequency voltage and current sensing and monitoring, largely propelled by the rapid evolution toward smarter grids. This progress owes much to advancements in sensor technology, device manufacturing, and sensor communication networking. The proliferation of low-cost, high-precision voltage and current sensors, along with their monitoring systems, has found extensive application across transmission lines, distribution lines, and substations. These precise distributed measurements furnish critical details concerning lightning faults, encompassing transient voltage and current characteristics like amplitude, frequency, and waveform.…
