Simulation Model for Lightning Overvoltages in Residences Caused by Lightning Strike to the Ground
IEEE Transactions on Power Delivery, 2010Lightning overvoltages coming from overhead lines, such as power distribution lines, telecommunication lines, and antennas to residences have been actively studied. However, the relation between a lightning strike to the ground and overvoltages in residences remains unclear.

Simulation analysis on lightning overvoltage of 500kV substation
IET Conference Proceedings, 2021500kV Nanning substation is the pivot of the power transmission from west to East.In the past 10 years, Nanning substation has been expanded and operation mode has changed. It will have a negative impact on the operation of the local power grid when lightning damage accident happened in Nanning substation.

Lightning overvoltages in low voltage networks
14th International Conference and Exhibition on Electricity Distribution (CIRED 1997 - Distributing Power for the Millennium), 1997The European Standard EN 50160 “Voltage characteristics of electricity supplied by public distribution systems” indicates that in low voltage power systems the transient overvoltages between line conductors and earth will not exceed 6 kV peak, but higher values occur occasionally.

Overvoltages in photovoltaic systems induced by lightning strikes
2012 International Conference on Lightning Protection (ICLP), 2012The high number of photovoltaic systems raises questions regarding their operational security even under extremely weather conditions like thunderstorms. Therefore a simplified model of a photovoltaic system, consisting of typical arrangement of solar-panels, was investigated.

Parameters Analysis of Measured Lightning Overvoltages from a Substation
IEEE International Conference on High Voltage Engineering and Application, 2018At present, measured overvoltages are relatively rare for the overvoltage-rated studies in power systems. The overvoltage online monitoring system developed by Chongqing University have successfully obtained thousands of valuable overvoltage data for ten

Lightning overvoltage protection for financial computerizing systems
Proceedings. Asia-Pacific Conference on Environmental Electromagnetics. CEEM'2000 (IEEE Cat. No.00EX402), 2002Financial systems are nowadays dependent on electronic data processing technology. One of the most frequent causes of failure in this highly sensitive system are overvoltages mostly caused by lightning. This paper describes how lightning electromagnetic pulse intrudes into computer information systems and causes system damage. Damage prevention is also
