Study on temperature rise prediction of ZnO varistors under multiple lightning strikes based on BP neural network and microscopic

High Temperature Materials and Processes
ZnO varistors are widely used in the field of lightning protection. After being struck by lightning, ZnO varistors absorb heat, which can lead to temperature rise and even damage, posing a serious safety threat to electrical safety.

Long-term field measurement and characteristics of lightning-induced overvoltages on 10 kV distribution lines in high-altitude mountainous areas and optimization of insulation coordination

Results in Engineering
Aiming at the lack of measured data on lightning overvoltages in operational distribution networks and the irrationality of insulation coordination based on standard lightning impulse waveforms, this paper carries out large-scale and long-term ...

Study on Transient Overvoltage and Surge Arrester Electrical Stresses in Offshore Wind Farms Under Multiple Lightning Strokes

Journal of Marine Science and Engineering
Lightning strikes are a major cause of wind turbine (WT) damage, with approximately 80% of cloud-to-ground lightning strikes exhibiting a multi-stroke characteristic. Therefore, studying the transient overvoltages induced by multiple lightning strokes is

Evaluation of Step Response of Transient Recorders for Lightning Impulse

, 2017
High voltage equipment will be subjected to several types of electrical stress during operation. A battery of factory tests is defined to ensure that the equipment will perform satisfactorily in service. One of the crucial tests is to apply a simulated lighting impulse as standardised to a double-exponential impulse with at front time of 1.2 µs (± 30 %)
