The study of voltage-current characteristic of lightning impulse to the metal-oxide varistor
Access is limited to UniMAP community.This project studies the voltage-current (V-I) characteristic of lightning impulse to the metal-oxide varistor (MOV). MOV is widely used in the low voltage equipment for protection from lightning surge.

Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...

Short Abstract Recent years have seen a steady rise in narratives of pronatalism and demographic anxiety, while younger people are increasingly expressing reluctance to have children for reasons related to climate change. This commentary argues that geography and geographers have much to contribute to imagining, researching and building alternative ...

The effect of multiple lightning impulse on the electrical characteristics of transient voltage suppression diode as low voltage lightning protective device [PDF]
The behaviour and performance of surge protective devices such as transient voltage suppression (TVS) diode under the application of multiple lightning impulses are different from the single lightning impulse.

Broken Mechanism of Straight Copper Wires near Terminal due to Lightning High Impulse Current
application/pdfWhen a lightning current flows through a copper wire, the copper wire would be broken at the terminal affected by electro-magnetic force. A straight thin copper wire such as 0.1mmΦ is melted due to the specific melting Joule integral: (j2t)
